Not sure what Kawi was thinking, but they increased fork rake-angle on 300, making it slower-steering than 250. Add +20 lbs and 300 handles like pig compared to 250.

Front suspension upgrade depends upon your usage and weight. Go to RaceTech's site and enter your weight into their spring-rate calculator and see how it compares to stock: https://racetech.com/ProductSearch/1...250R/1986-2007.

You'll really want to use dyno-tuning to dial in mixtures once you have exhaust installed. Don't get rid of air-box, you'll have issues in cross-winds and really no benefits (no more power than K&N in stock airbox anyway). Factory airbox poses no restriction to flow, so removing it won't gain anything.

If you have factory handlebars, and they're bent, pretty much gotta toss them. You can replace them with 36mm clip-on handlebars. Lowers bars about 2" and you can replace just bar section cheaply if bent later.

If you already have clip-on handlebars, you can just buy some 7/8" (22.2mm) tubing and replace just bar sections. I usually keep 11" section in toolbox for quick replacement at track.
