New Yamaha Subframe With JGRMX Adjustable Mod
If you're looking for a brand new Yamaha subframe with the JGRMX subframe mod already installed, this is your best option. The modification will allow you to adjust the subframe by just over one inch, by lengthening or shortening, to achieve the perfect seat height for your preference. Titanium hardware with threaded aluminum bungs are welded onto the frame. Set as a lowered subframe, this is a popular option for shorter riders, or those who want their seat height on their Yamaha lower for indoor racing. Comprehensive, easy to follow instructions are included.
