I´m 6´8" and 330Lbs. I have sat on the KLR650 and really like the way if feels. I don´t like the way the suspension goes down about 6" when I sit. Feels too weak! What´s the least expensive way to fix this? I like the look, fit and price, but I don´t want to spend an arm and a leg to fix the issue. Any feedback would be appreciated.
