I developed a high speed wooble, this past summer. I tightened the steering head bearing, which cured the wooble. I then decided it was time improve the handling, overall. I installed Racetech springs and emulators in the forks, and Works performance shocks in the rear. This firmed up the suspension quite well. The forks now recover quickly after braking and the bikes goes through turns level. Prior to this, the forks never fully recovered in a turn and I had to stay on the gas to keep the front end up. The stock rear shocks caused the rear end to squat down, under acceleration, and the front end would lift up causing the steering to feel too light and unstable.
I have a frame brace and fork brace on it and solid motor mounts are on the way. Sean is working on a notched and braced swingarm. A Marks exhaust will also be installed( lighter weight and better sound). Next I have to figure out what to do for rims. I really wanted Carrozzeria rims. Their light and came in 18 inch diameter. I like the look of 18 inch rims better. 17 inch rims will track a smaller radius around a turn, but I'm not trying to make it handle like a sportbike and prefer the look of the 18 inch rims. Unfortunately, the only options left for 18 inch rims are heavy. A lighter rim has less gyroscopic effect , making it take less effort to cause it to change direction. Hopefully, I can find another option for lighter rims, in the next couple months. I hate to be putting in all this time and money, and still have rims and tires as heavy as stock.
Hopefully, this coming spring everything will result in a good handling solid ride. I don't expect it to handle like a sportbike, but I always liked my Vmax because I think it's a good compromise between a sport bike and a cruiser. And nothing else looks like it! Except another Vmax.
