What would be a good sprocket set up for the following:
Mugello 186
Li 150 pacemaker
I have a 47 clutch sprocket and a range of front sprockets - an 18 gives me 4.8 in fourth - would this be a good set up?
Many thanks in advance

Your choice of exhaust will be a major factor..........

Yes it should pull that gearing with a clubman exhaust though.
Best of luck.

I felt my Pacemaker with the same kit and BGM exhaust was geared too low so I put a standard 150 box in and it pulls well in top with more speed but you do notice more sluggish acceleration but you can't have everything.

I went for 4,98 with 46-17 on my pacemaker box with a RT195 and MBGM CLubman. It gives me enough of both worlds regarding speed and acceleration in town.

Thanks for replies. I have managed to get a 46t clutch sprocket, what are recommendations for the front sprocket with this???

Hi m8 a lad I know had a mugello 180 kit with Li 150 box he had 15x46 sprockets which I thought was just right with a a/f 42mm box exhaust, he was advised to try a 16 x46 but he sold it before it was fitted
