    MT-09 Forum
    Hi Guys Noob + First post here.:confused: VERY keen on buying an MT-09, but want to know how Euro 4 has hurt the engine performance etc and what can be done - example, the R1 can have a new exhaust fitted, remove the sensor and servo and its better than before. Can something similar be done...
