On a business venture to our gold supplier in Germany I went sightseeing and to look at the bike dealers. Anyways I drove by one and slammed the brakes then parked and went in to look, what I saw was this.   But would this be possible to do with a Buell? I don't know if it would help or rob agility or not, having hub center steering. It's no prototype, you can buy them but they're expensive, something like 20,000 quid or 34000 USD. | ||

Its called a Vyrus by the way. | ||

Its more or less a Bimota Tesi. Very nice bike. Jens | ||

I think the placement of the radiators is as interesting as all the other stuff... | ||

I'm a big fan of funny front ends, epsecially those without sliding elements. It's obviously easier to integrate something like that into a clean sheet design than an existing production bike. Looking at the Buell XBs I'd think you could redesign the engine cradle to also hold the front swingarm, but then again it's only held to the from with 3 1/4-20 bolts so maybe not... A better approach I think would be to adapt a leading link setup to the existing triple trees. A similar thing is done on converted sidecar bikes. The real benefit to these systems with by changing swingarm lengths and angles, and by having that second link to form a parallelagram (gold rod above the swingarm on the Vyrus), you can tune weight transfer, wheelbase change, and brake anti-dive. Anti-dive (in this context, not the stuff from the 80's that made the forks stiff when the brakes were applied) is a wonderful thing, especially with brakes as grabby as the Buell's. | ||

The reason Buell's have telescopic forks is because they are cheap and effective. Buell was looking into doing something radical and different, and nobody wanted to build it for him. You can also bet that it would add a pretty penny to the MSRP. Could a suspension like pictured be rigged up to a Buell? Well anything can be done with enough time and money.

Every time I look at that bike I see rodends every where I have spent a career in Aviation changing wore out rodends. I wonder what it would handle like with loose rodends. | ||

I'm more than sure that if one was going to be spending 35,000 USD on a bike like a Vyrus, I would check every square millimeter of the bike before every ride. Hell, I'd be afraid to get it dirty so I probably wouldn't ride it often enough to loosen up rod ends. However, I did find this. www.tryphonos.com This guy actually builds and races HCS bikes here in the UK. I have no idea if he would modify a production bike or not, I'm sure he would for the right price. | ||

I think the placement of the radiators is as interesting as all the other stuff... That's what I noticed first. I'd be afraid something might jump off the road and damage one. Pretty sick looking bike overall IMO. | ||

I know two people who have Yamaha GTSs, and the consensus is that when things in the front end are out of whack, handling gets weird, and it becomes difficult to right them again. That thing above probably will work very well, but need constant attention. | ||

Now I'm starting to see why a simple fork, rather than a second swingarm of sorts, would be exceptionally simpler. What about a basic swingarm with a pair of shocks? I reckon it could work, but I work in a dental lab, so I'm no engineer though I do some metal fab once in a while. Or what about just a mono shock? That would be much lighter versus two shocks. | ||

There's many variations of funny front ends. I suggest Tony Foale's book, Motorcycle Handling and Chassis Design. http://www.tonyfoale.com/ | ||

Oooh la la, funny front-ends galore. Definitely some odd front ends. Grazie Mille. |
