I really haven't had a chance to check this out yet. But is the clutch system on a 1200GS a closed system and uses mineral oil rather than brake fluid and never needs changing?

Yep! No need to mess with it unless there's a problem.

Does the 1200RT have the same system?

Can brake systems change to mineral/hydraulic oil? The only difference I see is temperature/expansion at the caliper. Hmmmm <<<)))

I wondered that too. I would think the seals are designed for one or the other.

As cjack points out, the seal materials compatible with DOT-4 brake fluid are completely different than the materials compatible with mineral oil. But the bigger problem (as if the material issue wasn't enough) is the thermal performance. Mineral oil will create vapor at much lower temperature than DOT-4 and when that happens you have *no* brakes.

p-shaw. Riding with no brakes makes you a better rider.

Ask Mac of GMR fame, he had no rear brake (removed for weight) on a R100RS (loud wheels save lives). Can you imagine Ft. lauderdale Fl to Fairbanks Alaska with no rear brake, including Pikes Peak:uhoh . Sorry Mac if you get razzed! :bolt

Oh...you're saying my R100RS had a rear brake? I only noticed it very much when I was removing the rear wheel.
