So its time to pull the trigger on a newer bike. I currently ride : Its a 1979 IT 400. It was a good beginner bike. Sooooooo much power (See 400cc two stroke.) although the suspension and brakes are garbage, it has served me well. Now im on to the next phase, looking at a 2006 and newer ride, and I have made the choice to go 4 stroke as opposed to 2. My main decision now is do I go 450 or 250. I am 6'3 215 pounds, And I ride mostly trails and logging roads, with a fair amount of desert and track time coming too. I was exclusively on the 450 path but read some things that have convinced me otherwise. I think due to my size and the fact I have ridden a bigger displacement bike almost exclusively, that I am still thinking I should go with the 450. I also think that its something I can grow into. What say you moto monkeys?
