I just wanted to share this amazing project with all of the two stroke fans out there. We just finished this factory level 2 stroke build after a year and a half of R&D, testing, changes, etc. The end result is amazing and we ended up with a 53hp rocketship that weighs 15 lbs less than the AMA minimum weight limit for that class! 201 lbs, ready to ride with an empty tank. We used a Varner Motorsports modified KTM 250 sx powerplant in a 2011 Honda 450 frame with production based Showa suspension including a SFF Showa fork, modified, valved and set up by MB1 Suspension. The entire engine cradle and billet engine mounts are hand fabricated and machined to accommodate the KTM powerplant. Racetech Titanium was instrumental in helping bring the weight down with all of their titanium fasteners, axles, brake piston and pivot hardware. The bike also utilizes many one-off titanium or alloy parts and heavily modified OEM parts as well. DLC coatings were utilized in many critical areas including the shock shaft, brake hardware and pins, brake pistons, select transmission parts, titanium linkage pivot bushings, and swingarm pivot bolt to name a few. It took over 500 hours of trial and error, testing, changes, extensive mods and many hours of scratching our heads to get it perfect but I feel this is the most refined 2 stroke conversion build anyone has ever done.
