Parts & Accessories for The Honda NSR125R & NSR125F Two-Stroke Sports Bike which must not be confused with the earlier NS125R and NS125F although the success of these bikes precede the NSR. The NSR125 models are restricted to make them learner legal, however a simple modification to the exhaust system will resolve this and greatly increase power all round. The NSR 124cc was succeeded in 2004 by the CBR125.
