search function won't work for me the last few days and I know its been talked before, I have 02 rk and leaning for a 21 seems like I remember some post about having to re drill the rear holes on newer bikes is my 02 the same way or will it fit without any mod. also my se came lowered an inch from factory will that be enough to counter the extra height I put on 2-3 ohlins so that raised the rear a .5 or so I am thinking that be around a inch higher in front does that sound ok

 

I would say your probably fine on the height, but that depends on the look you like. I personally like the frame to run about 1/2" higher in the front. I assume by drilling you mean't the fender holes. Usually can either drill larger or dremel the holes to oval a little and get the fender to rock. Tape some closeline rope around the tire and check for clearance. I've had some work without drilling but always check, you don't want to have to repaint a fender just cause you didn't take a little extra time. Good luck.

 

just drill rear fender holes to 3/8 and it will be fine but check it like you always do when you do mods.
For the height, you will see if it looks like you want and after you can lowered. My buddy with his '02 RK didn't lowered.
You will love 21"!!!

 

Put the wheel on and tape a 1/4 inch thick something on and spin it if it rubs open up rear holes on fender. A 21" will be 1.5" taller than the 16",you may wan't to lower the front.

 

can someone tell me how much tire you have from the rim to the outside on your 120 70 21, the measurements i get from charts on the net don't match real world i need around 1.5 to level the bottom of my frame
