I have the chance to buy a 250 or 350 Gripper and wanted to know what bike is better? I also wondered if parts are available and where can I obtain them? Many thanks for any advice.

I'd go for the 250 everytime! although i think the 350's yellow looks nicer! the 250 version always gripped better in mud, never rode the 350! it may be better on rocky going with more revy power at hand? strange styling and they feel quite high up on the pegs! but balance is good so is the suspension! could have been a world contender if ossa could have got top riders but fate played its hand once again!!!
