Radial tires
« on: November 28, 2011, 02:23:31 PM »
I've read quite a bit about putting the radials on a K75.  I currently have 100/90-18 and 120/90-18 bias Lasertecs installed.  I have a 1986 K with the rear drum brake.

It appears I can go with 110/80-18 radial front.  But I'm not sure what to do about the rear.  If I go the radial route, I want to do radials front and rear.  Does anybody know a radial size to fit the 18" rear?

I'm not interested in swapping wheels.  If I can't just swap tires, I'll probably just try a set of Pirelli Sport Demons or maybe Bridgestones or just another set of Metzelers.

I've had great results with radial on front, bias ply rear on my K1100LT. Can't believe the improved handling.

Just got a set of Lasertecs on sale at Bike Bandit, $187 delivered and they give $10 credit and Bike Bandit $ as well.  140/80 on the back.  Too good of a deal to pass up.  Now if I can find a good deal on battery.................and fix the leak in my tank..........

Use one of the "metal" epoxies that is gas resistant.

All 3 of my Ks have been fixed with this epoxy and not one has leaked again in 4 years and is so much cheaper than welding.

 So here is the "fix" I started today on the tank leak, good olde JB Weld.  Am thinking about several small thin layers applied over a long period of time.  Looks worse than it really is, but hard to take a picture in a dark tank!  The spots are just reflection of the flash.Hahaa.



Thanks for all the help and contact for battery.

That's all great and everything, but what about a rear radial tire for my 86 K75? ;D
