I also loved the idea of building a 450cc sportbike. Basically a SM with bodywork and layed out with sportbike geometry. There was a series in CA a while back that had this class, not sure if they still do though. It never seemed to catch on anywhere else. Always wanted to ride a 2 stroke aprilia too
If you all are really Into all of these bikes check out Roland Sands. He really builds the coolest custom bikes. If nothing else it can give you some ideas for your own projects
Ive been following the gp moto and 4 moto designs for a while now. There is a company called GpTech who makes a lo of the items you would need to convert a 450 into one. Imagine a YZ450F with a complete R6 front end and a rear shock shortened and revalved/resprung and some TZ250 bodywork. Oh man that would be fun!
I am not concerned with its power to weight ratio. I have owned plenty of powerful bikes. This is a chill bike.
I was enjoying his flip flips and the wobbly car wheels and that fact that the engine didnt idle haha. Somebody with some video skills needs to remix that vid with the theme song from the movie
There used to be a big bore kit for the 350s that allowed them to run 450 pistons. The SL 350 K1 was 45-50 pounds lighter than the CB or CL models and tipping the scales around 300 pounds. I put the kit in my buddies K1 and the compression was 235 psi. Remember 100+ pump gas? Made for a real good Tillamook Burn hillclimber, Back To Backs, Big Burtha etc. The motor eventually made it into a Maico frame and I don't remember if we ever weighed it. I have had my eyes open for a good deal on a K1 for awhile. Everyone seems to know (so far) what they are worth though.
