Servus,

new Parts for two Bikes!

First the new Rearwheelcover for the Orange One:



Second the new Fairing for the White one:



More in the next few Weeks.

Servus,

the White One is finished for 2012:

from the front:



and right side:



The orange one and the chopper are still under construction.

Cool.

The dual calipers have any advantage over a twin disc setup or is it just for looks?

It does provide more braking.A little unusual but Jim always thinks up new ways to get things done.

the white one is looking great!!

I think the white one is so ugly I like it.  Now if you could just let dropit paint it, it would be perfect.

Servus,

The brake must be so because it is the braking of the rear wheels. There would be a caliper too little and therefore have built two of them and they, too, now outstanding. The whole thing was also approved by the German TÜV.

The next bike then what is tasted like.

Just curious, and maybe I missed it earlier in the thread. But how did you solve the ratio difference between the master cylinder and having dual pistons to fill when braking? Did you use a master cylinder from another bike that was made for a larger CC piston caliper?

I can't answer for Jim,but an 88-97 GSX600/750 Katana has a 5/8 inch Nissin master cylinder.The GS5 sports a 1/2 inch unit.It should bolt up on a GS.

I would think by doubling the volume of the calipers you would need to double the volume of the master cylinder to keep the correct ratio. Anything less and you may not have adequate pressure for full brake application.

I also wonder if the added friction to one rotor would quickly overwhelm the rotor and cause heat warping.

I love that he was thinking outside the box and trying something different though.

Servus,

it was used a caliper to the caliper of the GS and GSXR. The master cylinder is a 5/8 of the GSXR 1100.

The braking effect is enormous, and there are no thermal problems with the brake disc.

This will on occasion even replaced by a disc from braking.

awesome, I'm glad it all worked out. I was just curious how you overcame all those possible issues. Like I said, I love that you are thinking outside the box, it shows real creativity.

Servus,

what else can I do, but to test yourself and try. But that's the attraction of custommizing.

Cross your GS is not too bad, I would obwhl obstruct a longer swingarm.

servus,

the new Bike is finished.



The new chopper project see here:



its an modifued BMW Frame from 1936!

Wow, I LOVE the look of that bike! I see why it's named "Prancer".

I like Prancer better than the orange bike that you did. Do get me wrong the orange one is a great looking bike i just like a more clean bike without the over the topness of the orange gs. Both look good and the orange one is a modifying marvel. On Prancer i like the seat and how you made it have the extra space between it and the rear tire. My hat is off to you sir.

Servus,

@ Knowles: Thanx for the compliments. Prancer on the bench is called by a German manufacturer Kreidler.

@ Kijona: The name comes from a reindeer Prancer of Santa Claus. All my Bkes get reindeer names.

Very good job as usual

Thanks.

So, next week i will start with a new Project.

USD Frontend
B12 Swingarm
Buell X1 Rearend
Nice Exhaust
Selfmade Handlebars

Pics coming soon.

Servus,

that is the new project by Jim Knopf Cycles:
