Frequently asked questions
CE or racing: what is the difference?
A CE exhaust is homologated and, in the homologated version as supplied, intended for public roads. A racing exhaust has no homologation and is intended only for closed terrain or the track. Check the rules in your own country for what is permitted.
What are the 70/80cc and 80/90cc exhausts for?
The Carbon Racing and the Cross Carbon are intended for a Rieju with a larger cylinder kit, so for a tuned engine. With the stock 50cc cylinder you will get more out of the Rookie or Cross Rookie.
Will this fit my Rieju?
Check which Rieju models are named in the product title: the Cross Carbon, for example, is only for the MRX / SMX, while the Cross Rookie also fits the RRX. If in doubt, send us the type and year and we will check it for you.
