there should be a tag somwhere on the frame that has 6? digits i think. They usually start with a W, There will be 2 numbers together Example, WS94?? The 94 would mean its a 94 model. If its 92 then its a 92 model etc etc. I never was the biggest fan of the 250cc engine as I always thought they were rather noisey and kinda weak. Smokinwrench is right about them in the fact they run absolutly perfect and then WAM, partys over. I have a 400cc in the shop right now that has suffered from piston explosion. Those 400's will flat out haul as well. I had a 400cc (2-stroke) Sportsman and from a standstill you could nail it and pull the front tires off the ground! thats a big heavy 4x4 so you can imagine in something like the trailboss 2wd that it would be nothing but stronger.
