How to make a 270kg bike stop better, plus some other improvements! Why should sportsbikes have all the fun! Get rid of 270mm stock rotors, replace with 320mm FJR rotors, holes drilled out to fit existing 10mm bolts, you can see the originals overlaid on the new ones here: Obtain some used six piston Tokico calipers, because they are cheap, like me! Mock it all up on the bike: Make caliper brackets out of 10mm steel plate as per measuring and some educated guesses, trin calipers here and there with a grinder and drill out mounting holes: Bolt it all together and bleed like crazy: Grin like a kid at christmas every time you brake or see your bike side on\\/ Bike went from a solid four finger pull to stop moderately hard to a nice medium two finger pull to detach your retinas.
