New to having a honda, im loving every minute of it but was wondering if anyone knew where to find any other brake and lever options and if they know whats the largest size tire you can put on the rear wheel i believe i researched and the wheel is 5.5" wide.

 

If you just want to replace the existing levers with an aftermarket set then Dennis Kirk is a good source as well as exoticsportbike.com.

 

Congrats on the new bike! The Wheel is 5.0 inch. There are many threads on here about moving up to wider rim with a 180 width rear tire and more.
