Yamaha Adjustable Subframe Mod
The JGRMX Yamaha adjustable subframe mod allows you to adjust the subframe over one inch, by lengthening or shortening the subframe, to achieve the perfect fit. Our subframe modification uses titanium hardware with threaded aluminum bungs that are welded into the frame. When set as a lowered subframe, this is a great modification for shorter riders, or those looking to lower the seat height for indoor racing. Detailed instructions are included.
PLEASE NOTE: You will need to ship your subframe to JGRMX in order for us to install the modification. Turnaround time is generally one week after receiving the subframe. You will need to pay online (here) before we will do the mod.
