Ok before eveyone tells me a 150 will fit I have a 2000 Fatboy with the MT90 B 16 on the rear. The 150 did not come into play till 2003 I believe. Does anyone know or have they put a MU85 B 16 on the rear of a 2000 to 2002 Fatboy.

Thanks

 

Yes, I have been running the MU85B16 on mine for the past 2 years. Sad to say it has lasted that long, not enough to ride lately. Probably have about 5,000 miles. No problems at all. Looks better and and gives a little more contact patch obviously. I think to do a 150 you might have to reverse the fender strut bolts. I'm quite happy with it. Hope this helps.

 

btw i have a 2000 fatboy

 

I have had that size on my bike which is a 2002 fatboy with no problems as well.

 

the mt/90 is a 130 series
the mu/85 is a 140 series
m/80 is a 150 series
any will fit no problem. reverse the bolts, and switch to the "button head". been running a 150 since new. 2000 fatboy...steve
