It certainly melts the cheese on my labias.

Personally I really dig the girder front end. I showed the picture to a coworker who's building a 66 Triumph Tiger bobber hardtail and he couldn't figure out how it worked. He kept calling it a springer. Nope, different breed of cat.

The exhaust tape has got to go though.

I read somewhere its called paralever or something like that.

Nope. "Paralever" suspension is a trademark name for BMW's rear suspension that's supposed to minimize suspension twist on acceleration. Their front suspension was called "Telelever" but that was just a trademark name for the Saxon-Motodd race bike suspension that they copied.

The technical term for the suspension on this Triumph custom is "Girder" and was popular on bikes before hydraulic forks were common. It's different from a "Springer" which was the other common front suspension back in the day. Both are a "leading link" suspension, but a Girder has the links to the steering head while a Springer has them at the axle. Generally speaking, a girder is considerably more stable and rugged, while a Springer is lighter and simpler. John Britten used a form of Girder on the V1000 race bike and it worked quite well. They guys that built the Confederate Wraith like it too, but more for form over function.

More importantly, the original Triumph Speed Twin used Girder front suspension.



Same idea, but not nearly as stiff as the modern incarnation.
