V4 Dragbike Streetfighter (MOC)

[Kierna]

A new way of putting 64.2x20s tyres onto their rims. Squeeze them onto the inner lip and be rewarded with curvy motorcycle tyres!

I wish I could offer you higher image quality... but I just can't see a reason to upgrade from my Nokia 6300 yet.

This bike is the later, matured evolution of a bike I built in 2010 (bottom image). It is a traditional streetfighter.

This bike has functional pullrod rear suspension ( ala Buell) mounted underneath the the engine.

It also has the motor barrels mounted on opposing 3x7 angled liftarms for a narrower "V" engine angle. This not only looks authentic, but allows the frame of the bike to be attached directly to the motor, whilst the swingarm and rear suspension ar mounted to the crankcases.

There is a 16 tooth gear at the center of the crossplane crankshaft, with a chin running to the front sprocket. No drivechain in these pics.

Nice, but the red motorcycle needs some rear suspension. It looks bare underneath the seat. The rear Technic Liftarms (supporting the rear wheel) seems a bit long.

Tut, tut, read the fine print Rear suspension mounted underneath the motor. It isn't visible, and is hard to explain.

In the not so fine print, it says dragbike.

For reference, a twin turbo ducati dragbike.

Looks good One of these days I'd like to build a bike too.

Thanks mate!

Bikes can be tricky, but there are easy places to start. Choppers are easy, because they are not at all compact, and have no rear suspension.

Rake is easy to achieve by making the steering head angle 90o perpendicular to the top frame tube.
