I"m a woods rider so a little difference is ok. I'd rather have the caliper protected...ur prolly right . the measurements are 4.25 / 1.75 . id go with 4-1.5 unless someone else knows better . that means with 4/1 that ull drop 1.5in in width under stock . wow thats alot to give up with ur 3/2's uve gained 1in . wander if u could get someone to fab u a guard to protect ur calipers ?
Stock is 4+1I bought some itp baja rims for my kfx450r and they don't completely cover the brake caliper. It leaves about an inch of the caliper outside the rim. I want to get the correct back spacing so the caliper will fit inside the rim.
