A small version of the ISR 6-piston caliper.
The OC/OD calipers is intended as a twin set-up for 250 road racers. The OG/OH can be used both front and rear and has
proven to be popular as rear brake on larger drag racing bikes.
The weight of the caliper is an amazingly 580 g., including pads!
The small swept disc area needed with this caliper means the disc becomes light too.
When Peter Lindén used this set-up on his Honda RS250 GP-bike the weight reduction was almost 2'000 g.
