For several years I have been making the Tri Glide Lift Brackets originally thought up by Jerry Lenard. Based on his design concept (getting rid of the rear sag) and my testing of different lift heights and bottom shock locations. All starting out just for the “more level look” of the Tri Glide. Then the ride testing for how it handled and “felt” on the road. I do not advertise the improved ride and handling qualities part but it was immediately reported through the forums and testimonials I received.
The looks part is very obvious, the ride part, at best is subjective. My “butt o-meter” has told me that ride quality and handling was greatly improved. To this point I was only guessing to why and wondered about how much if any, the weight was transferred on the TG. Today I decided that I would do a few back to back test.
My test: I set up three race car scales to weigh my TG at all three tires. Then I took three sets of rear shock brackets. Stock, tGLIDEstuff 1.25 Lifts and a set cut with 1.25 lift and shock angle set rearward.
Test riding each set (butt o-meter test) and weighing at each tire for comparison.
Results: I did not remove anything from bike between tests except some gas was used so weight of overall bike varied a couple pounds.
Stock brackets: Total Bike Weight 1270
Front Tire: 348 / 27.40%
Right Rear: 460 / 36.22%
Left Rear: 462 / 36.38% Frt 27.4% / Rear72.6%
1.25 Lift and shock angle moved rearward: Total Bike Weight 1273
Front Tire: 350 / 27.5%
Right Rear: 461 / 36.22%
Left Rear: 462 / 36.3% Frt 27.5% / Rear 72.5%
tGLIDEstuff 1.25 lift bracket: Total Bike Weight 1272
Front Tire: 348 / 27.35%
Right Rear: 461 / 36.25%
Left Rear: 463 / 36.4% Frt 27.35% / Rear 72.65%
With me on trike, static, weight distributed real even front to back.
When I weighed trike with me on it / 182 pounds
Front Tire 403
Right Rear 523
Left Rear 528 Frt 27.72% / Rear 72.28%
(Just a little movement in seat changed rear side weights only)
This was done at David Parkhurst shop. David has years of experience fabricating and setting up race cars. When he saw what I was going to do, he stated that I would see little to no change on “static” weight distribution with just changing rear height. This type of setup shows itself in movement and handling. What I call “butt o-meter”. But I had to know. Glad I am not a betting man, I would have lost the ranch! Then on the change to moving the shock angle, he stated shocks are built for certain loads and certain angles. This also matched information I had from several dealers interested in the lifts. First thing after proof of Product Liability Insurance, they would install only if shock angle stayed close to stock. I tested a set anyway, what is a few hours among friends?
Back to stock: Sags like a loaded down sow. WOW, after more than 30,000 miles with lifts, it was night and day. A slight low speed wobble over bumps. Stock is so hard to steer going into corners, accelerating out, rear seemed lighter, reverse of what I would have thought. Weight in motion, needed to experiment and feel to believe. I think I also felt every rock on road, like going from a Caddy to a Vega.
tGLIDEstuff 1.25 lift: Looks great with rear lifted. Corners like it is on rails. Sitting position better. Ride night and day different from stock. Smoother and no sudden or unexpected steering movements. No slow speed wobble over bumps.
1.25 Lift with shock bottom moved rearward. Same as standard 1.25 lift. No softer or harder ride, same handling.
I had been through allot of testing before, both height and shock placement. As I have always stated, I found my original brackets just right but I felt handling was better because of front being loaded more. It may be in motion but not static. Lifts do not change the overall static distribution percentage of weight. But ride it and magic happens!!!!! We all like magic, right?
