Started life as a TaG kart with a 125cc two stroke. I executed the engine swap myself about two years ago. Parted out a 2008 KTM 450 SX-F for the motor. Previous owner of the bike had put a high compression piston, and I added a few internal carb mods to improve throttle response. Unmodifed motor had 54hp, compression increase and freer exhaust should put it right around 60hp. Far more reliable than any kart engine, with about 10x the service intervals.
