Can some one out there explain to me what the benefit of having a 16.5" front wheel is? Do you benefit from the smaller circumference by tuning in faster into corners? Do AMA pro's use this set up? Seems like a lot of people have them, also seems like the tires are more expensive.

It's not so much the smaller size of the wheel, as it is the design of the tire itself. 16.5" tires have a larger aspect ratio for one. A 17 may read 120/70-17 where-as a 16.5 will have an aspect ratio of 80 or more. Primary benefits are better handling through corners and reduced chattering. One of the tire guys here would have a better explanation of the physics of it, but yes a 16.5 makes a considerable difference.

They are more expensive because they are a limited production. Especially in a supermoto compound. 17's are widely produced for many bikes and it brings the cost down. When the AMA had a series...all of the factory teams, and most of the privateers ran 16.5.

I've run both sizes of front wheel in the past, and currently run a 16.5 and will not go back to a 17 on the race bike. For a street application, they are not practical.

What you mean to say is " it enhances the griptivity" :rofl:
