My brother purchased this after market muffler and rear rack for a Kawasaki KLX 250, but decided not to purchase the bike. They are manufactured here in Chiang Mai, and are a popular addition to this bike. They are brand new, and have not been used. Think the normal price is about 8000 baht, but I will sell them for 6000 baht. The parts are currently here in Chiang Mai. Please contact me at 084-100-1203.
