Tecnigas Next R performance exhaust Yamaha engines

OK for racing! Tecnigas has been making exhausts in Europe for a long time, and the quality, light weight and excellent cost-performance is evident. This is the popular "Next R" model. Use this exhaust on standard 49cc engines or with big bore cylinder kits for more performance. This raises the peak output power through its supercharging effect at higher RPM. Expect more acceleration and higher top speed from this exhaust. You need an unrestricted CDI too to take advantage of the higher powerband - most Japanese-made Yamahas after 2002 will need a derestricted CDI. Taiwanese market Jogs (Jog Fun, Jog Cabin etc) do not need a different CDI. Carburetor tuning may be required, and lighter weight rollers will need to be fitted (not included). To meet European regulations this exhaust may be fitted with one or two restrictors - these can be easily removed. To suit: Yamaha models- Jog, Axis, Vino, Aprio, Champ, Aerox etc all two stroke with horizontal engine Taiwanese models (with mounting mod)- Adly Silver Fox SF-50, Gatecrasher GTC-50, GTA-50 and Roadtracer RT-50 Bug Jive And other European bikes with Minarelli type engine. As there are so many different makers using the same basic engine, modifications to the exhaust bracket may be required depending on the model. SAMPLE IMAGE SHOWN, the actual exhaust has a different shaped header This exhaust when set up correctly will increase power output from your engine. Rejetting/roller tuning must be done by a qualified mechanic or experienced person. Testimonial 21 Jan 2012: "I recently purchased some bolt on/in mods for a VMoto Monza eg: technigas exhaust and lighter variator roller weights. The difference these bits made to the scooter is quite amazing given the 50cc rating." W.C., Wellington
