I have an 88 600, and I dont mean to complain but the tires- the rear especially- has more sidewall than probably most dirt bikes. Its kind of a "learning" bike so dont want to drop a ton in it. How much can you alter dimensions of tires on motorcycles- if you can at all, and what would be a good brand to start looking at?

being its an 88 its not gonna give ya alot of choices.
basically the tire sizes work like this

150/80/17 means ---------

150 is the tire WIDTH in MM
80 means the SIDEWALL is 80% of the tire width
17 is the rim diameter

if you have a 140/150/80 you could go up ONE size safely but you CAN NOT GO to a WIDER tire with a SHORTER sideway, that will mis-shape the tire and make it handle badly in the corners.

so what 88 600 do you have and what size rear tire does it have ??

It is a 130/90-16 in the rear. Kind of cracked on the sidewall too. There are about 20 different kind of tire brands out there too- think id probably be best off going with the stock brand. Maybe like a Dulop 140/80-16.

I think you would be happier with the Bridgestone Battle axes BT-45's, Pirelli Sport Demons or Metzlers ME33/ME880.

By the way are you sure your rear is a 16? i think its an 18???? Either way that rim will not take more than a 140 in there safely.
