Hello ,

Is there a direct fit between a 1988 K100 RT non ABS frame and a 1994 K1100 LT ABS frame ?

Thank you

I've just gone the opposite way taking off a '99 1100LT frame and fitting the engine with an '87 RS frame. Yes they are a direct bolt on fit to the engine, gearbox, radiator, steering head bearings, bodywork.

Differences:
-1100 frame has thicker wall, heavier tubing and different bracing at the steering head (stronger, heavier). You might have difficulty fitting the 8v fuel tank to the 16v frame due to the different cutaway under the tank
-the mounting points for the pannier frames are wider(further across the frame) to match the wider paralever rear end.

Thank you , good info.
