The Malle Mile Seaside Race Winner from Stibnite Moto…
Some name him the “07 King.” Dan Stone aka Danners of Stibnite Moto has earned a reputation for himself turning as much as Malle Mile occasions on loopy machines of his personal creation, a lot of them powered by Yamaha’s 689cc CP2 parallel-twin, which powers the MT-07, XSR700, YZF-R7, and Ténéré 700.
Launched in 2015, the CP2 has been known as “the very best parallel-twin bike engine ever made.” The motor has roots within the engine of the Paris-Dakar-winning XTZ750 Tremendous Ténéré,, which spawned the TDM sequence of machines powered by liquid-cooled DOHC twins.
“We are able to see that MT-07 is a refinement of the TDM idea as a result of its single front-mounted stability shaft, vertically stacked gearbox shafts, and YZR-M1-derived (Yamaha’s MotoGP engine) four-valve head end in a smaller, tighter, and lighter package deal that may match into extra sorts of bikes.” –Cycle World
In accordance with Cycle World‘s Kevin Cameron, these engines are typically particularly powerful and dependable. Their cylinders are forged in a single piece with their higher crankcases, and the oil sump and pump are situated instantly beneath the 270-degree crossplane crank. With the liquid-cooling, they will run compression ratios of 11.5:1 and better, producing severe torque, and we’ve seen them have success in each flat monitor and circuit racing.
In recent times, nonetheless, he’s been tweaking, tuning, and constructing customized bikes round Yamaha’s parallel-twin, pushing the envelope of what’s already the corporate’s most versatile engine. We’ll be bringing you many of those CP2-powered creations within the coming weeks.
Immediately is the “Stibnite Stinger” — aka the “Seaside Bike” — a machine constructed for the 2023 Malle Mile Seaside Race, completely fabricated round considered one of Dan’s beloved MT-07 mills — engines he often picks up from eBay or the breakers.
“I wished a uncooked and enjoyable stripped-back bike to race within the limitless customized class of the Malle Mile — one which seemed nice and was useful.”
The body is a one-off tubular metal chassis designed to carry the CP2 engine. Nonetheless, with lightness one of many supposed targets of the construct, Dan opted for aluminum when it got here to the swingarm, subframe, and bodywork.
The Stinger is rolling on 21″ / 19″ motocross wheels with full knobbies. Whereas Dan hasn’t managed to weigh the bike but, the Stinger is clearly far lighter than anything powered by Yamaha’s parallel-twin engine.
“She’s a stripped again uncooked beast that craves bouncing off of the limiter…a Swiss Military knife of a bike…”
As you may think, 75 horsepower in such a light-weight package deal ends in one severe sand ripper:
“It’s an absolute hoon to trip. Picks up and goes like loopy. Loves being bounced off the limiter with the again finish hanging out. Primarily raced on sand and grass, you end up turning with the again finish. A bit of stomp on the rear brake to get it in and a handful of throttle to get you out.”
The actual check of the Stinger was the 2023 Malle Mile Seaside Race on the Margate Sands, the place Dan got here out as the general winner — congrats, man! And he additionally completed second general in the principle Malle Mile Pageant.
Dan isn’t resting on his laurels, nonetheless, and neither is the Stinger. He has plans for taking his two-wheeled Swiss Military knife on streets, ovals, and even…water.
“After 4 years of makes an attempt (and 4 customized Seaside Race bikes…), Dan lastly gained ‘The Malle Seaside Race’ this Could. After lifting the trophy on the rostrum, his first phrases have been… ’I’ve accomplished my dream, so what’s subsequent?!’ Every week later Dan got here again with a query, a loopy grasp plan and a sketch!” –Malle Mile
That’s proper, Malle London has secured permission for a single 1/8-mile “Moto-Surf” run for 2024. Says Dan:
“Subsequent 12 months it’s the massive quantity 10 for Malle London, so put it in your diaries to see us skim throughout the gorgeous Grimsthorpe Fortress lake.”
