I have a 2000 rk and I ordered a 21 front 18 x3.5 I noticed today that I have maybe 1/8" of space between the belt and tire. And what is on there now is 16x3 and the rubber is a mt90 16. Will my new fit

 

I am going up on my size too. I just ordered 18x3.5 for both front and rear I got the RC Components CZAR. I was told that the only difference between and 18 and a 16 are the size of the rim. Just make sure you are using the same size tire as the 16 and all will fit. Never increase your tire size. Not a good thing when it comes to handling and fitment.

21 for the front... I am sorry but I can't help you there.

Oh!! I have a 1994 FLHTCU don't forget to make sure you get the right axle size for your bike.

 

It'll fit the front no problem depending on which fender your running that's all that may need changing but that part of the mod game .
