Hi all...firsy time on...I found a way to lower the frame on the suspension on a XB12 without compromising the muffler/ground clearance. I built a low profile aluminum muffler (slightly louder than stock but much lighter) and changed the handle bar configuration so I can slide the forks up through the triple clamps about a inch or so and made a custom link to lower the rear shock. It handles better on the dirt, power slides any time, still a little scary though so I'm still experimenting to get it dialed in.
