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. This Tecnigas Next-R system is delivered with grey anodized aluminium silencer, complete chrome expansion chamber and all needed fittings and brackets. The chrome version of the next-R is not only a successful design, but also features long-term protection against corrosion. With E-certification. The manufacturer has changed the colour of the rear silencer from blue to silver. Some are still blue damper supplied from stockpiles. Please inquire before ordering from us, which colour is currently in stock (if the colour is important).
