Yes, thanks guys, we're just trying to tell the truth about how these exploding cigar four striker MX bikes have almost ruined the sport. The 2-4 project bike is a 2001 YZ400F frame with a '79 RM250 motor stuck in it, fit like a glove. The most difficult part was cutting and re-welding the expansion chamber into a down pipe (we love down pipes). It will weigh around 210-214 lbs and put out 38 horsepower.
It should haul ass, and become a template for all those poor bastards with a blown up four stroke sitting in their garage that they can't afford to fix.
We should have it posted tonight sometime. Rick did it for off-road.com, so you can see it there too (part 1). Keep the faith guys, KTM is still pushing two stroke technology, and a direct injected two cycle is right around the bend. It will combine a four stroke type lower end, with a two stroke top end, but eliminate the loop scavenging with a high pressure injector and a variable exhaust port.
Thanks for reading!
