Going off tangent of the topic a shade...

I was at a NASMoto race back around 2004 and saw a guy ride a clapped out XR600R with a street 21 and a fairly worn old Sport Elite on the back, won the race topping a couple proper new KTM Supermotos in the process. It's mostly rider when pure horsepower and speed are of lesser value.

But I'd say a DRz400SM would be pretty nice for a low buck wonder. Sweet rides in spite of a lot of people whining about the 5 speed gear box. My friend has no problem goofing around on the back roads at 80mph or cruising the dirt roads at a lower speed.

 

Pretty much all "sport riding" is based around corner exit speed. If you're leaving corners on tight public roads at faster than 80 mph and continuing on to higher speeds than that you're going to lose your license or wind up in worse trouble than that.

The change in velocity from corner entry to exit is gradual enough to be handled by a single.

It's hard to use more than about 45 HP. People with 600s spend about 3% of their time at wide open throttle. People with 1000s never do.

Add that to a racetrack derived frame on bumpy public roads and you have a recipe for disappointment. Even New England racetracks like Louden not fast enough to support very fast 600s or 1000s.

Even with all this said, 17 inch rims for a KLX250s that isn't built are a poor investment.

 

Yep, but the single will still handle as if on rails and hold speed very well. And as I commented and gave example too, I agree the 17s are more for appearances than function.

 

yea thats what i thought about the 17's as well, i just got my set of oem rims, need a sprocket ad chain kit and tires and im done, anyone have good recommendations for a good dual purpose tire, maybe 70 street 30 offroad, and what gearing combo should i do? right now i think its a 14/48 but it was dark so the front could be a 13, i like to ride highway but still want low end torque
