R90s fork brace interference

So I bought metzler lasertec tires months ago to make the old girl a roller while I tackled other items on the list standing between the lift and the road.

Many done, and others close, I went for an evening gawking session, and I noticed the front tire rubs the brace. Badly. Found some chatter online about the lazertec not fitting the /6 brace. Also, the /6 fender must be modified to take the /7 brace which would clear the tire(allegedly).

My first thought was to get an outside the fender type brace.

Can anyone confirm the fit issues? The tire clears the fender brace if set at 5 psi btw.

The /7 brace has more clearance, fits a wider tire. But to make a /6 fender fit a /7 brace the fender has to be trimmed. I did this with a RotoLoc tool. Think rotory sander. I sanded the indentation of the fender that fits on the brace. It might have been a 1/4 inch till the fender fit flat. It's not very noticeable unless on a concours machine or something.

The /6 fender brace is not available anymore. I tried to buy one. If you ask for a /6 brace they will sell you a /7 brace with out blinking an eye. It's what the book says fits.

Great. So i either get different tires, hack(or replace) my fender, or spend 200 bones on an outside brace.

/7 braces on eBay for 30-50 including shipping. I hate to cut the body parts on this bike, but I'm trying to be frugal here. It's def no show bike. But if I ever do sell it, I don't wanna hear "oh, someone hacked the fender, bummer" from a buyer looking for a restoration project.

That's about it. You could also throw in a drunk to make the pain last longer.

LF,

Just a note that I think might clear up a confusion. The /6 fender is not only longer in the back and uses a stay to help it not flop around it has more side to it. If the fender is an upside down U. The two uprights of the U are longer on the /6. It covers more of the side of the tire. The grinding needed is not on the inside of the U but on the longer sides. Make them shorter. The amount needed again is very small and by blending this a little it is hardly noticeable.

Maybe there wasn't any confusion but I thought there might be.

I dont like metzeler tyres,. I have found that on uk roads they white line badly once they have a few miles.
a 3.25 Michelin or a 3.25 Bridgestone bt45 fits fine on my 75r90.

If you get a San Jose type brace, the brembo ones won't fit on a ATE. Etc etc.
