My hat is off to whoever found that caliper would work on our bikes! Dave or whoever it was has done a great service! I was already running a 290mm rotor (rather than the stock 265mm) and noticed a improvement with the stock caliper. Yesterday I made a simple adapter and put on the 2 piston caliper and combined they WORK!!! Just trying it easy around the block it seemed better without even breaking-in the used pads that came with it, but when I grabbed a handful of front brake HARD at 25mph it locked up the tire!!! With 2 fingers now you can hear the front tire slip on the pavement. 3 fingers will now give me a panic stop brake effect in front!

The spacer made from 3/16'' steel was pretty easy.
Anyone doing the conversion should be sure to get the banjo bolt with the 2 piston caliper, as it fits the stock brake line but the threads are different.
Anyone running a 80's cast wheel no longer has to get the solid rotor and turn it down.
If someone, (MMranch) wants to go even further, the caliper from a 04' Suzuki Bandit 1200 appears to mount the same way and is ''3 PISTONS!!!''
