World’s First Five-Rotor Car Looks Like Le Mans, Screams Like A Banshee

“Mad” Mike Whiddett is an expert drifting competitor with a ardour for rotary engines. Beyond simply tuning Mazda’s manufacturing facility choices, he additionally builds his personal, and his newest creation is probably probably the most wild. Whiddett created the world’s first five-rotor powerplant and commissioned a improbable car to suit round it known as the 787D.

To put a five-rotor mill into perspective, a Wankel engine has a roughly triangle-shaped rotor spinning round an eccentric shaft, and every of the three sides goes by way of the consumption, compression, ignition, and exhaust phases of the combustion course of through the rotation. Most road-going Mazda fashions used two-rotor engines, and the Le-Mans-winning 787B had a four-rotor mill. 

 

“Mad” Mike took issues a step additional along with his five-rotor engine. The engine reportedly displaces 3.3 liters, in accordance with Carvibz. Unfortunately, no particulars concerning the energy output can be found, however we have reached out to Whiddett for extra particulars. The video above confirms the powerplant feels like an absolute monster. The exhaust exits simply behind the entrance tire, that means there is a very quick run from these spinning rotors to spit out the combustion gases.

The Japanese tuner Rocket Bunny is chargeable for the wild physique, allegedly based on the fourth-generation (FD) Mazda RX-7. The tube chassis and radically altered engine recommend there’s not a lot left from the unique sports activities automotive, although. 

 

Whiddett premiered the 787D at Mad Mike’s Summer Bash 6 on December 2 in New Zealand. He plans to make use of it for drifting, however there aren’t any movies exhibiting the ludicrous machine sliding round but. We stay up for seeing how effectively “Mad” Mike can kick out the tail and make this beast howl. 

If you need your individual 787D, you may, however do not anticipate to drive it. Hot Wheels released a tiny model in 2023 that may match into the palm of your hand. 

It’s value noting that one other builder created an even larger 12-rotor engine by arranging a trio of four-rotor setups in a triangular layout. However, there isn’t any proof of this powerplant going into an precise car, not like Whiddett’s mill.

THE WEEKLY FEED: BITD: 1978- YAMAHA WINS EVERYTHING • PRO VERSUS SCHMOE VIDEO

This was a post by Dave Osterman, Mike Bell’s mechanic. He notes that Honda had a great year, but back in 1978 Yamaha put together a decent run.

This Yamaha ad (below) features the 1978 500cc National Champ Rick Burgett, Bob Hannah- AMA Supercross  and 250cc AMA Motocross champion and 125cc National Champ Broc Glover all wearing their #1 plates. Of note, Hannah also won the Trans-AMA title in 1978 and Heikki Mikkola won his second straight 500cc World Championship.

Not too shabby…

Skyler Howes, who was dropped by the Husqvarna Factory Rally effort after finishing third at last year’s Dakar, has joined the Monster Energy Honda Rally Team to race the Dakar Rally and World Rally-Raid Championship.

“Riding for the HRC rally team is a highlight of my life and career.” Says Skyler. “I learned how to ride on an XR75 when I was three-years-old and I began my rally effort on a CRF450X so my roots are deep with Honda. To also have the support of Monster Energy is huge for me and I’m super excited to see what the team and I can accomplish together. After a podium at the Dakar my focus remains the same, have as much fun as possible, and continue to reach for the top step of the podium.”

Of all the machines I have ridden and raced, the KTM 300 stands alone as my favorite mount.  I can remember going to Blackwater with Rod Bush and testing their brand new 273 in 1986, raced the entire Qualifier schedule in ’92 aboard one and then did Six Days in Czecho. As the years have scudded by the machine has morphed from linkage to PDS and now offers both. The front end has evolved from Upside down WP’s to right side up Zokes, and then back. But the powerplant has always had one special attribute; it makes traction down low and pulls a higher gear in the tight ugly stuff. This was the main reason I love this machine both then and now!

THE WEEKLY FEED: SPRINT ENDURO WORLD CHAMPIONSHIP • INCREDIBLE HARD ENDURO VIDEO • YAMAHA IT 200 BITD

Mike Webb was testing a 1985 Yamaha IT200 for Dirt Bike magazine. This was filmed at Indian Dunes (Wolf’s FM2 Nikon) in the Santa Clara river and marked the early stages of editors using fill flash for outdoor action. The bike was new, with the engine moving from the 175 to a full 200. This was achieved with a longer stroke, resulting in improved bottom power that proved crucial for the small bore machine. A new frame shifted the steering head 20mm rearward compared to the 175, and a 20mm longer swingarm provided the same wheelbase but with a more forward weight bias, significantly improving the steering. The bike was sold for $1749.00.

SPRINT ENDURO WORLD CHAMPIONSHIP

By Shan Moore
Johnny Girroir: “I felt at home in the woods, as I always do. I kept it consistent and was lucky enough to keep it on two wheels all weekend. I definitely need to clean it up in the cross test. I just wasn’t happy out there. I had a couple good times but nothing crazy. So, I definitely want to work on that a little bit. I had fun. Layne and Dante were flying out in the cross test and Josh laid down a couple of heater enduro tests. Just I guess consistency paid off and I kept it on two wheels.”

The Sprint Enduro World championships took place over three days at High Voltage Raceway on the Pennsylvania/West Virginia State Line. The event featured top sprint racers from around the world, including 2016 Individual Overall ISDE Champion Taylor Robert, former World Enduro Champion Jack Edmondson, and UK Pro 2 rider Jay Baxendale. These riders competed in a format that included four runs daily on two tests – a grass track and a rugged enduro test – over the three-day Labor Day weekend.

Layne Michael definitely showed his speed in the cross test, winning three of the 12, but just couldn’t catch Girroir in the enduro test. “Honestly, it came down to one crash in the enduro test yesterday and that’s where I lost the bulk of my time,” said Michael.

After three days of racing, KTM’s Johnny Girroir emerged as the winner of the Sprint Enduro World Championship, finishing ahead of Layne Michael by just 15 seconds after completing 24 tests. Dante Oliveira, also racing for KTM, started the event with a six-second win over Girroir in the opening cross test. Michael came in third, five seconds behind. The battle for the win between these four riders lasted all three days.

Dante went on to win two of the final three cross tests on day one but lost time to his competitors in the enduro tests. Girroir made up the difference with dominating wins in three of the four enduro tests, securing the day-one win by five seconds over Michael. Craig DeLong from Rockstar Energy Husqvarna finished consistently in third for the day. The top six was completed by Dante, Toth (who won the final Enduro test), and Mateo Oliveira from FMF/KTM Factory racing. Pro 2 rider Jack Edmondson from the UK placed 11th overall, while the Pro-Am class was won by Jason Tino from Magna1 Husqvarna in eighth overall.

This was only the second sprint race Josh Toth had raced all year, but he managed to get up to speed by the second day. “It was a blast,” said Toth. “ I was a little rusty and just pushing the edge and crashing too much on day one. I dug myself out of the hole yesterday and just tried to survive the tests today. Rode pretty well, but they were getting nasty and these guys were shredding.”

Although Girroir won only two tests on day two (Sunday), he maintained his top position in the standings. Michael and Dante Oliveira showed their skill in the cross test, with each winning two of the four tests for the day. Dante consistently posted some of the fastest times on the cross test but fell during the second cross test.

Tenth overall and top Pro 2 rider was former World Champion Jack Edmondson of the UK.

On day three, Dante won all four cross tests but had a crash in the first enduro test, costing him nearly two minutes. Michael outperformed Girroir in all four cross tests but Girroir made up the difference in the enduro test, securing a 15-second advantage over Michael in the overall standings, with Toth finishing third.

Overall Results:

  1. Johnny Girroir (KTM) 2. Layne Michael (GG) 3. Josh Toth (GG) 4. Craig DeLong (Hsq) 5. Ryder Lafferty (GG)
    6. Dante Oliveira (KTM) 7. Trevor Bollinger (Hsq) 8. Mateo Oliveira (KTM) 9. Taylor Robert (KTM) 10. Jack Edmondson (KTM)

Here we are up in Gorman, CA- testing the new 1984 Honda XR500R. This was a much improved machine, it had lost some suet, had improved Showa suspension, a dual carb setup to improve and smooth the power and had a radial 4-valve combustion chamber for enhanced compression. The power was tractable and strong, starting was still an issue (at least for a guy who had only spent 4-stroke time on his CB160) and despite the diet, it was still a beefy sucker to manhandle slamming the scales at just under 300 pounds. At the time I was racing a 1983 CR480 in District 37 Enduros and loved it!

DEATH OF THE 500 2-STROKE: CLASSIC DECOSTER

Mike LaRocco earned the 1993 500 National Championship, but never got to defend it. The AMA no longer recognized the class from 1994 forward. How could the 500s go from being the most prestigious class in motocross to being dropped? In the December, 1993 issue of Dirt Bike, Roger DeCoster told us how it went down.





Congratulations and condolences to Mike LaRocco. Last month he wrapped up his first 500 National Championship. Unfortunately, it will also be his last. In fact, it will be America’s last. Mike will never even get to ride with his #1 plate, because next year there will be no 500 class in America.

Even in Europe, the 500 class is taking a back seat, with the FIM directing TV coverage to the 250s and the manufacturers directing their teams likewise. What happened? How is it possible that the 500 National Championship, once the most prestigious class in motocross, has come to an end? It’s a complicated issue, but in truth, the 500 class hasn’t suddenly dropped dead just now. This is only the burial. The class actually died, or at least began to die, back in the early ’80s. That was when various forces first started to combine to eventually result in this situation. The first factor was the rise of Supercross as a 250/125-only sport. Open-class bikes simply weren’t suited for tight stadium tracks, so they were excluded and relegated to outdoor-only tracks. It didn’t take long for manufacturers to realize that Supercross was where the bulk of MX spectators were. Soon, most of each company’s development effort was concentrated on the 250 class. Marketing executives wanted their teams to win in front of the big Supercross crowds, so the factories went all-out and made major changes to the 250s more often than the other models.



Mike LaRocco rides with his number one plate on his KX500 for a Dirt Dike Photo shoot. He never got to race with it, at least not in the U.S.

The next blow to the 500 class came in the form of a worldwide sales slump in the mid-’80s. Motocross bikes were less affected by the slump than street models, but nonetheless the factories suddenly had fewer resources to draw upon for racing. Suzuki and Yamaha made the first big cutbacks, deciding to stop competing in the 500 class in both Europe and the U.S. Their Open bikes had sold poorly–Suzuki stopped manufacturing its RM500 altogether. In the U.S., that left Honda and Kawasaki as the only two manufacturers to support the 500 class.

Another factor was the changing nature of track design. Outdoor tracks became more and more like supercross. It was only natural–spectators got used to seeing riders get big air in stadiums and began to expect it outdoors, too. Also, young riders wanted more jumps. They had grown up learning to double jump before they even knew how to ride down a rough straight. Those kinds of tracks are more suited to 250s.



Jeff Ward’s 1990 KX500 was almost the same bike as LaRocco’s in 1993.

So, now we get to the point where there are not enough teams in the 500 class, not enough riders and not enough bikes. It was time for the burial. At this point, it seems silly to point out what could have been done to save the class. Some action would have been better than no action, though. While I don’t have all the answers, I think the class could have been saved if early action had been taken, both in Europe and in the U.S. In Europe, the FIM is notorious for ignoring problems or denying that they exist. It would have been possible to design tracks with Open bikes in mind, for example. It’s kind of boring to watch a 500 on a really tight track, but the sounds and the power that a big 500 makes when it has a little open space are exciting in a very different way. I think spectators would respond to that and be eager to see 500s in the right environment. That, in turn, might have brought more sales to the 500 class.



Roger DeCoster performed his own 500 shootout in the pages of Dirt Bike in 1995. Click on the image above to see which was his favorite.

Another possibility might have been to enforce the production rule in just two classes while the 500 class was left open to works bikes. In Europe and in the U.S., each class could have its attraction: The 500 class would be for works bikes, and maybe even four-strokes in the future, the 250 class for production-based 250s, and the 125 class for younger riders. Now the 125 class has the most rigorous travel schedule in both Europe and the U.S. In America, the 125 outdoor schedule is as long as the 250 and 500 circuits put together, and in Europe the 125s are required to travel to South America twice in the series. With less travel and perhaps an age limit (or a champion-moves-up rule like the U.S. had), the 125 class would be cheaper for manufacturers as well as privateers, allowing budgets to be stretched to cover all three classes.

At any rate, the time for thinking about what could have been done is past. It’s more beneficial to think about the future and what will fill the place of the 500 National series here in the U.S. I think the AMA’s plan is a good one. The 500 class will be replaced by a new six- to eight-race series called the “Fall Classic” (interesting how it could become a classic before the first race is run). By the time you read this, the new series will already be underway. The attraction of the new series will be the fact that it will be open to any bike over 250cc. No weight limit, no production rule, two-stroke or four-stroke, as big as you like. In a way, it’s an attempt to revive the old Trans AMA series.

The rules, or the lack of rules, might stir up some interest in big bikes. Someone like Eyvind Boyesen might send a rider to test some new ideas in an actual race. I don’t think there will be many works bikes from Europe showing up, though–basically, there aren’t any, aside from Jacky Martens’ Husqvarna four-stroke. Still, the possibility is there.

Whether or not he rides, I think that Martens will have an effect on this new series in the U.S. He just won the 500 GP title in Europe on his thumper, becoming the first rider to do so since Jeff Smith did it in ’65 with his works BSA. On top of that, Joel Smets finished third on a Husaberg four-stroke this year. This seems to be generating a resurgence of interest in four-stroke motocross. This new class is a natural for four-strokes. In the future, it might even be conceivable to change it to an all-four-stroke series, although if that were to happen right now, they might have a hard time filling the gate. It will be interesting to watch and see if interest keeps going in that direction. The sounds alone might be enough to draw spectators to big four-stroke races. I have even heard that Honda has talked with Martens about testing a new four-stroke in Europe next year, with the intention of racing it in ’95. Wouldn’t that be an interesting twist?

So while I would be dishonest if I said the death of the 500 class didn’t disappoint me, I think it’s pointless to mourn for it now. The future actually looks more exciting than it has in years. Motocross, as always, is in the process of big change–and change isn’t such a bad thing.
