The old G/S forks have been known to break - but extremely
rare, under extreme abuse only. BUT mine were straightened on day one, and now has a lot of hard miles on it with a better brake than standard, so I figure it's time to upgrade.
I'm installing a set of R100GS forks on my R80G/S. Went through all the various options, and gave up due to megacost for the good ones, or lousy brakes on the dirt bike versions.
The standard G/S brake is pretty sad, I changed to a 4 piston Performance Machine item a long time ago, with a K100 disk. I'm going to upgrade it again now that I have better forks that won't flex under braking.
A dirt bike brake is adequate for a dirt bike - but a fully loaded G/S at speed - I don't think so! DOUBLE the weight! Look at what they put on the R1100GS and rethink.
I'm thinking a 6 piston caliper on a 310-320mm disk. Decided against dual disks because of the weight, and a skinny 21" tire is probably inadequate traction.
