recently i have been deciding to buy either a kawi 250EX/R or a 500 ex/ R. Im 17 and have already took and passed the MSF, which i recommend to anyone. But, i'm not sure of how comfortable i will be b/c im 5'7" and 145 lbs. I rode a 250 nighthawk for the MSF and had no problems touching ground. I dont plan on buying a zx6r b/c of the cost of the bike, power, and insurance. Also what do you guys recomend for gear? Also is there a difference between the EX and R models?
