I have had my 2005 kdx 200 for 1 yr and i can say i am very pleased with this bike. The only thing I would like to improve is the low-mid range torque it just seems like gears 1 and 2 are hurting a little bit on the soft sugar sand. please give me some aftermarket pipes and silencers you recommend. also i was thinking of replacing the handlebars what bend, brand, etc. work well with this bike? thanks
