Ive said it before and i will say it again, motion pro cables suck ass. Ive always used oem cables.
Then last year i said to myself "im going to try those pretty looking SS braided cables" (clutch/ throttle) Yes they look cool and all but thats about it, both were a lil short i got them to work but then both broke within a few rides.
I will Never run anything but the trusty OEM cables from now on.
Keep them lubed up really well and they last for years of smooth operation.
Theres a few story's just like yours on here also about this same problem of fitment.
Im sure some people have had good luck with them, but ive seen/heard more bad then good.
Only heard this the last few years though, maybe long ago they actually made them quality and now they have someone else making them for them to save $$$, who knows.
