XR680 build/rebuild

My personal bike:
full rebuild with Falicon rod,680 kit, Applied clamps and CRF steering damper, coated frame etc..
Enjoy.
More to come.

That looks great mang. Can't wait to see the finished product.

Something like this ... but a little different in colors.
I build this one a time a go for a friend.

I've seen the stuff you posted over on Supermotojunkie.com very nice.

Here you find some stuff...

First off, let me just say that is one SICK bike... I'd love to have that...

Secondly, a couple questions;
Did you fab up that rear fender yourself; the stocker w/ like a CR 250 fender?
Did you custom build that header? I've always liked the header wrapped around the other side of the engine design; seemed to make sense w/ the way the exhaust port is angled on that side.
Lastly, is that carb the FCR? It looks like it, but I'm not sure...

Thx

The rear fender and panels are from a crf450 '05 : cut and modded to fit,underneath sits the OEM fender (cut).
The carb is a first generation FCR carb (road racing),oval bored to 43mm by the Dutch VHM firm.
I rode the bike today (run in) and the power with the 680 is insane,lifting the front when he comes in the meat of the power (3000 a 4000 rpm) even with 15 x 40 sprockets.

Been neat to watch this come along.

Good on ya!

iI Manu,

What tank do you use on your XR?

Denis

It's a Monnier tank with modded '03 CRF shrouds. It's a Swiss firm: http://www.spracing.ch/

In Italia they make alu tanks with CRF '05 shrouds : http://www.blitalia.com/catalogo/dettagli.php?cID=2&pID=5

I must say, that's the FINEST xrr I have seen, wonderful work.

PLease compare the performance between the 650 and 680 kit.
What compression are you running?

Thats an inspiration to me. I was thinking to do something like that with a XR 650R and now I found this work. I'm curious, you have any video with your XR?

hi mate i go 1 of 2 engines built for worlid supermoto its 780cc cant wait to get it complete

The pictures are dead, someone have there on his computer please ?

Thanks for your answer...
She is very nice... My new model ahaha
You are too on suoermotojunkie no ? I had see a near motorbike

I would see this page later, Thank you very much
All of Xr were yours ?

The 680 is mine, others are project bikes for clients or to sell in my shop.

You make a great job ... the last bike (10 november) is nice, a lot of work
I would to think about put my bike into your hands; you accept french XR ?

Between 650 and 680, you had a lot of difference ?
I have never read a report about this preparation and I would to remake my engine ... so it's could be interessant to know.

Bring those French XR's on ! Je parle un petit peu le français.

680 is alot of torque , combined with the right mods (stage 2 cam,big valves,big carb and special CDI) it's sometimes scary...but tooo much fun.

Je ne parlez pas Francais, je m'excusez - however, don't you think it's atrocious voor een Belg om dit niet te kunnen?
680/650 = 1.04 >> 4% more torque for a 680cc when compared to a std bored one!
You also say "a lot" more, quite like plenty dudes do on the net..... but it's only a measly gain of 4% ?
I'll never do it, boring out the perfect nikasil bore to gain what, next to nothing? Suuure, cam, valves, carb etc, but if you do that to a 'std' angine then you basically have the same - less bragging rights of a 'big bore' engine of course.
Quite different if you hop-up a 250 to 300 or 320 or thereabouts, that IS a real difference!
My 2c's, feel free to splash out dear dollar on a 680 kit
