Yamaha have drawn lots of praise for the looks and technical spec of their new YZF-R125, now LeoVince up the performance and looks stakes with their SBK-GP complete exhaust system. LeoVince have put their racing expertise to good use with this bike, the design of this system runs a tuned header pipe from the engine, into a small expansion box (replacing the power-sapping catalyst) then connects to the superslim SBK-GP rear silencer. With attention to detail like deburring and polishing of welds, plus the streamlined shape of the underbelly box, pipework attached with race springs for flexibilty, this exhaust really is the business! The massive 20% torque gain for a small 125cc bike proves how good the LeoVince engineers are.
