i dont think it would be a good idea its way much thicker i mean thats the oil i use on my wrx i think reg oil is best for the bike

i was wondering if it would be a good thing to use this now that i have some miles on the bike. Repsol 4T Synthetic 10W40. my buddys that i ride with put it in there bikes. and it seemed to have made them run a little smoother. but they are all on 600cc bikes that are 4 cylinder.
any input would be good.
