Motorcycle Forum / General / Motorcycles / September 2008Check out the Drawing for HD Front Wheel Trike
I found this article posted at www.discountharleystore.com/news It has drawing submitted by HD for a Front Wheel Trike that leans into coners...... Looks like it would be a fun ride.

Looks like it would be a fun ride. Very interesting. But stupid. The whole idea of putting the two wheels up front on independent a-arm suspension is to keep the tires FLAT on the ground so you can use ALL the width of the rubber while cornering the short wheelbase trike as hard as a car. > The whole idea of putting the two wheels up front on independent a-arm > suspension is to keep the tires FLAT on the ground so you can use ALL > the width of the rubber while cornering the short wheelbase trike as > hard as a car. I was behind one of these Can Am things (http://www.motorilive.com/wp-content/uploads/2008/07/bombardier-can-am-spyder.jpg) some weeks ago, and I watch quads every now and then. I can see how cornering flat with wide tyres gives you nice lateral g's. However the concept of riding on these things like on a motorbike seems wrong to me. When cornering hard, you can see how much force the rider has to bring up to stay in the saddle, compared to a leaning motorbike, where the rider ideally has just to compensate for the additional gravity and no side factor. I think if something wants to corner flat, it should have a car seat. Comparing the Piaggio MP3 (you start seeing more of them on the street, colleague rides one) which is a rather relax and effortless ride. cu .\\arc > I can see how cornering flat with wide tyres gives you nice lateral g's. > However the concept of riding on these things like on a motorbike seems > wrong to me.

I think if something wants to corner flat, it > should have a car seat. I was considering the design of a non-leaning front engined front wheel drive three wheeler a few years ago. I initally thought of obtaining a Yamaha V-Max and bolting a space frame in front of the steering head, and retaining the motorcycle seat for an exciting passenger accomodation. Imagine being a passenger on such a vehicle while it is cornering at 1- g lateral... There have been quite a few built which were essentially three-wheeled cars with motorcycle engines, and some had cozy side-by-side passenger accomodation. Such designs that use a donor motorcycle, bolting the motorcycle engine and frame to a tubular space frame up front, become rather longish, and tend to look like a grand prix car when complete. I spotted one such creation in a service station and stopped to look. This particular one-off vehicle used a Honda CB350 donor motorcycle. It had two Honda motorcycle wheels up front with two vertical forks to act as king pins. The imaginative steering mechanism was a steel *cable* that wrapped around the steering column multiple times and the cable pulled the wheels instead of pushing them in the conventional manner. Engine location determines length and weight distribution. One grand prixesque design had the driver sitting beside the engine. But I think the best design would have the engine up front and probably should have front wheel drive to avoid running a long drive shaft (or chain) through the passenger compartment. The machine I was mentally designing would resemble a guitar pick in plan view and would be quite low to the ground with the driver's butt just a few inches off the pavement. The vehicle would be lower than, say, a Triumph Spitfire. When driving a Spit, you could look up under the fenders of American cars at stoplights... I figured that the three wheeler would need a flag on a whip like a dune buggy so other motorists would notice the motion, even though they couldn't see it. But I got stuck on figuring out how to design a stylish roll cage that would allow the driver to see where he was going, but prevent him from being decapitated by running underneath a truck... > I found this article posted at > [quoted text clipped - 4 lines] > > Check it out at ---- www.discountharleystore.com/news And a 640KTM powered job...... http://thekneeslider.com/archives/2008/09/28/brudeli-654l-leanster-on-the-road-i n-europe/'); >> I found this article posted at >> [quoted text clipped - 8 lines] > > http://thekneeslider.com/archives/2008/09/28/brudeli-654l-leanster-on-the-road-i n-europe/'); and for those with a sportier idea for a 640...... http://thekneeslider.com/archives/2008/09/29/ktm-640-lc4-single-cylinder-track-b ike-project/'); |
