carefull running any lower than a 45 rear with a 14 front tho mate.
I ran a 14/44 at aintree last month, and wore thru the rubber chain runner, and then wore 2 chain shape grooves into my swingarm. No harm done, but the chain was red hot
much better to run a 15/47-48 than a 14/44-45

point !

and exactly why my 600 runs 16/42 instead of the 15/38 it was on.
