Apr 27, 2007 · The only potential mechanical problems with an '86 R80RT are in the transmission, BMW having deleted a locating circlip. This affects all models '85-'94, the circlip only returning at the very end of production. Since this engine was originally designed to be 750cc, the increase to 800 is minimal and the 800 engine is very smooth running.

Jun 10, 2004 · I have alway considered the R80RT to be the definitive early 80's airhead for BMW. It was the combination of sport bike and touring bike, the first real sport touring bike! Just the right size for one up touring.

May 21, 2012 · R80rt I owned an 84 R80RT. Many carefree miles. Smooth running and plenty of power. Loved the sound from the dual exhaust. The only drawback? I did not have a battery tender at the time and seemed to always have a dead battery! Other than that, there were many features on the R80 I preferred over my current 04 R1150RT.

Jul 3, 2020 · I've joined the community to see if you can help me diagnosis my problem. The bike is a BMW R80RT, new to me, been driving for a year, about 80K+ on it.

Mar 11, 2012 · Turns out that the on-line BMW parts fiche has a bug (checked on MAX and Bob's websites). The '81-84 R80RT is shown as having the old /6 under the tank master cylinder setup instead of the correct handlebar mounted version. Motobins shows that the bike has a handlebar mount master but offers overhaul kits for five different diameter master ...

May 14, 2013 · Has anyone had any experience changing the final drive on an R80RT? I have an '86 that I resurrected from 20 years in some guy's garage. I'm a little surprised how fast it spins at speeds I need to do (80 MPH is 5,000 RPM). In So. Cal. …

Apr 27, 2018 · That o-ring is often the source of continued leakage after installing a new piston kit. And finally, it’s half the labor to replace instead of rebuild. Don’t forget to order new crush washers for any banjo fittings. I think Bob’s BMW has 15% discount until the end of the month, if that helps with the cost decision. Best, DG

Aug 29, 2021 · I try and use inch-sized tires...my experiences with metric tires was not that satisfying years ago. These are the spec sizes for the /7 and maybe for the twin-shock bikes.
