Honda RS125

Through our own racing activities we have now developed many replacement and performance parts for the RS125 ND4 model, mostly for the 1984 to 1986 model years. Through our development partners we’ll keep you on track. Our growing list of products will not only keep your bike looking fantastic but also lower your lap times with the best quality and performance available. We aim to keep all common parts in stock to avoid any delays.

We have built a number of engines and full motorcycles for competitors in the CRMC Post Classic GP125 championship with great success.  If you have, or would like an RS 125 for this championship please call us to discuss any requirements you have.
