Nope, I need it lower than stock, not higher. However 48 seems a bit too low.

A 46 would probably be ideal, or a 13 at the front, which is what I wanted in the first place...

 

i would suggest a bigger rear for sprocket durability +2 or +3 rear

 

I must admit when I changed from 14 to 13 on my KLX150S I wasn't keen on changing the front; I always thought the norm was to change the rear.

However a 13 front was all that was available and what the other guys were using, so I went with it.

Having said that, I used that 13 tooth front for 18 months and it was still fine when I sold the bike to get the 250, despite adding a big bore kit etc. and using the bike exclusively off road.

But yeah, I feel more comfortable with a bigger rear than a smaller front, just seems more durable and less intense somehow.
