Pro Circuit Works Pipe

Pro Circuit Works Pipe

George S - Auburn WA Great Sound "We run Pro Circuit Works Pipes on all our bikes. My son's KX100's are always getting compliments at the track for how great they sound. I am sure there is a performance improvement as well but I haven't ever dyno tested vs a stock pipe. I do know they make the bike sound way faster! Great product!"

aaronj1010 - Lufkin, Texas Excellent Fit! "Extremely happy with this shirt, other reviews said it fit too large, but my adult medium is an excellent fit and the sizing is spot on. My overall experience with Motosport has always been a positive one, and I look forward to purchasing more from you guys in the future!"
