The Tecnigas Next-R is a well-proven and all-round exhaust for 50cc or 70cc sport cylinders. This exhaust has a good performance yield at relatively low range and sound levels. In terms of performance, the Next-R system is an improvement over the Leovince TT and, with the correct tuning, can reach over 9bhp. The Tecnigas Next-R system is delivered with black anodised silencer and all necessary parts for installation and brackets. This exhaust features an E-certification and is thus approved for use on public roads. The included general operating permit (ABE) is issued for Yamaha CW50 (BW50).
