Most Recent Dirt Bike Parts Reviews

Nuetech Nitro Mousse

Nuetech Nitro Mousse

Westy - PA
5 out of 5 stars
Please read for KLX 300r "The 100/100-18 size in this does not fit the KLX300r rear tire (Dunlop MX52), nor does the 110/100-18 as I was told it would by Nuetech. The 5 star is not for Nuetech, they were no real help in finding the right mousse for the stock tire on this bike. You should look to another company for mousse to fit the rear on the KLX300r. The 5 stars is for the great way Motosport handled my refund and the 5 star customer service they showed taking care of me. Nuetech 0, Motosport 5+. Thank you Motosport. Awesome way to stand behind a customer."
