Tilting 3 wheelers are getting to be old hat, after Piaggio introduced the MP3, there was a flurry of attention and activity related to the technology and it looks like it works very well. Now both manufacturers and homebuilders are turning out their own versions and there seems to be a ready market. So, yesterday, I get an email from Thomas Melcher of Wesll Corporation with a bit of information about his Wesll suspension, a 4 wheel tilting mechanism that can be used in place of the usual non-tilting suspension, replacing the 4 wheel setup as found on an ATV or the 2 wheels as found on a motorcycle. I took a look at his website and it got my attention.
Tilting 4 wheelers are not new, the Chrysler Tomahawk concept had closely spaced wheels with a small amount of tilt and Yamaha had a concept called the Tesseract, also a tilting 4 wheeler, but concepts were the end of it.
Tom began working on this idea when his brother was injured in an auto accident. After doing some work, he came up with the configuration where the entire leaning mechanism was placed outboard. After a lot of refinement, he says it works perfectly. The Wesll suspension certainly seems to be very well developed and Tom says the prototype quad, shown above, weighs only 310 pounds! Nice.
The video below shows the Wesll quad in action and if you watch it, you'll immediately see how well this suspension works. This is quite impressive, it has the kind of lean associated with the Brudeli Leanster but with 4 wheels it has more stability. The videos of the sportbike concepts shows how far it leans, it's not limited like the MP3 and looks like a rider could do some very serious corner carving with twice the traction available.
One thing Tom was very clear on was that this is not available as a kit. He is working to have this licensed through OEMs and he really hopes they stay with 4 wheels instead of trying to adapt it to 3 wheelers for ease of licensing. I can only imagine what your state DOT would do when trying to register this and, unfortunately, that could be a real issue. It would be awfully frustrating to have technology that works this well and no way to use it. Motor vehicle laws may need to adapt more quickly.
The Wesll suspension is very cool technology, I like it!
