The Orange Project rear monoshock upgrade

The Orange Project and the TR-1 share basically the same frame so, like I did before with the TR-1, I decided to upgrade the rear monoshock on the Orange too.

I took the chance to raise the whole bike a bit and "re-do the math" for the front rake angle.

Yes, I know, she doesn't look good

After a bit of machining..

...everything is ready.

On the right the original monoshock, on the left the new multi-adjustable one taken from a Yamaha R1...with an orange spring of course....

All in place, checking the new height

Back on its wheels

A big thank you to my friend Emanuele who helped me with the whole process

Shit happens...

Not my fault this time, I swear...

Now I have a new relic hanging on the workshop wall

Great...

You will see it only if you know it's there...

In the attempt of keeping down the temperature under the seat of "The Dirt-One" (all the electronics packed in such a small place can become very hot), I decided to turn all the alluminium plate under the seat in a big dissipator.

Also made an extention to act as mudguard/airbox

It looks like the rear diffuser on sports cars

Almost invisible when everything is in place... but you know it's there..

Thanks Enrico!

The TR-1 Top Yoke

In order to set the right ride height and bike geometry, I had to fabricate a new top yoke to raise the front end a bit

Halfway through

Done.

Machines are great, but nothing beat the "hand finish". So, after several hours of smoothing, sanding and buffing, here it is .

Actually this is only the first round of polishing, the detailng will be done later on the build.

Other than brace the forks in the new position, the round-ish design let the top yoke "hug" the usual Plan-B-tacho-pod and keep it closer to the rider.

There is still room for some pilot lights and toggle switches...
