Hello guys, new to the forum. Just added an MT03 to me collection and although I like this bike it does seem under geared. 5000 rpm brings 70 mph. Most other bikes seem to aim for 4000 rpm at 70. I'm wondering if the previous owner changed a sprocket. Anybody know what standard sizes were on a 2012 model?

Also, it is fitted with Leo Vince exhaust and bangs a lot on overrun until fuel has burnt. Is there a fix for this?

Hi bud got s 2017 model can't answer your question but did your after market exhaust make it go a lot better. I have a stock exhaust still on mine did you at all take the baffle out??
