The 919 Project Begins

Right then....

I just introduced myself the other day in the new member forum... thanks for the welcome!

I have had designs on a 919 for sometime, and I finally scored the bike. I bought an 04 and I planned to ride until december or so before I started down this road but my hand was forced... My good friend (since high school) is the Motorcycle guy from the TV show on Velocity called Fantom Works.

After seeing the bike on Sunday he went to town...

Bike started like this



We are in this state after half the day Sunday




Now that you've seen the state here is the plan:

I have acquired & installed 929RR front calipers, rotors, and master cylinder
I have a 929RR rear caliper on the way

I plan to:


Pull motor, and detail, possibly powder coating valve cover and oil pan.
Install Pairs block off plates.

Pull and bead blast the swing arm, rider, and passenger pegs & mounts, and the swing arm mounts then have them powder coated black.

Ohlins Rear Shock

Tank & Tail stripped and painted VW Vortex Blue

Remove undertail exhaust and replace with Delkevic 900RR Header and Termignioni Carbon muffler

17/44 520 Chain and sprocket setup.

And finally here is where i need help/clarification

The front end:

Im planning on the RC51 setup that has been discussed by a couple of you guys Helimech, and HRC27

The CB1000R Trees are the way to go I understand.

Fork tubes... I have a line on complete SP2's in good condition, what is the bottom line... I see both you guys used SP1 tubes

Will I really have an issue moving forward with SP2 legs?

I didn't have plans to tear into this until the dead of winter, but since I have this to ride I guess ill just have to crack on.



obviously all assistance is greatly appreciated.

Read through HRC's post on the RC51 swap, its quite informative. The 929 rear caliper bolts right up but the line mount and the bleeder are reversed so be aware

SP2's are no good for this swap .... unless you install the guts in SP1 tubes. Dan do you have that pic that shows the SP1 vs SP2 tube differences regarding the taper & spacing? That pic explains it all.


urdrvideo ..... you say you installed CBR929rr rotors as well? On what wheel?

I noticed that the SP2 tubes have a longer tapered section at the top... does this section not allow the lower clamps to have ample enough area to affix?

In reading the description it makes note of not having as much adjustability in the clamps.. honestly they would be all the way down anyway with the tops flush to the upper clamp....

He in lies my confusion and need for clarification.

well... I have 929RR Calipers with some kind of sweet rotors with gold anodized centers... on the stock wheel.

I'm not near the computer and this phone app leaves a little to be desired for searches so I can't find the side beside pics of the SP1 & SP2 forks. I do know in order to use the CB1kR triples you need a very special set of alien technology shims made from unicorn tears

To securely clamp the SP2 forks you would have to raise the fork leg in the CB1000r clamps .... making them really short and unstable.

If you install SP2 forks in CB1000R clamp with them at the proper ride height the lower clamp will be riding on the taper ..... and not secure/safe.

The CB1000R clamps are relativly flat, while the RC51 stock clamps steps/sweeps down so there is different spacing between the upper and lower clamps & they are positioned differently when stacked up.

You can run your SP2 forks but you'll need to source some SP1 outer tubes, like I did. I bought new-not cheap for sure. You'll need a set of Helimechs shims for the bottom triple too.

SP2 outer tubes will not work with CB1000R clamps. Once fitted you cannot slide them down enough to get your length, trail, etc, right.

My pleasure brother. If you ever have questions on how I did my bike, send me a PM or email [email protected] . I had Helimech and Voodoo help me and they were a big help.

No worries man .... if I can be of any help just shoot me a PM as well.


Your build list sounds very similar to my 919 build so I have lots of useless information stored away on the subject material.

I don't recall how much difference there is between the length of SP1 vs SP2 fork legs, but if the CB1000R triples are going to cause headaches for your project, you could try S&P triples:

Hornet 900 | Style & Performance - eShop

$800 US

Those are some sweet-ass triples but it's
a little less to get the CB1000R's plus new SP1 outers. I've got the CB1KR's handlebars too. Sweet bend.

EDIT: About the same after shipping I bet.

Yeah I don't mind spending money but that's a bit much... Besides do we have any idea what forks they work with?

I "think" he has SP1 forks but I "think" SP2's would work if you got the top out springs modded. Race Tech makes a set.
