style and performance triples

how strong do you think S&P triples are at handlebar mounts for 919.
It looks like S&P took their standard top triple design, drilled holes and installed bar mounts. Why can't one do it with let's say rc51 sp1 flat top triple?







stock RC51 SP1 top, it's a little more than 7 mm thick on top:

Keep in mind that the RC51 component is a casting that has been machined.
The billet items will have superior strength of materials properties, the only question there being by how much - which will be a function of the alloy they used. Personally, I just don't feel good drilling and tapping into thin section areas for something as critical as a steering input mount. Hopefully it's fine and dandy and they did their homework well, although I'd be very careful about how much torque was used and use loctite.


I would not drill and tap the RC51 clamp.
Some unease with the S & P design, but hopefully A OK.
They sure look nice, and the lower looks super rigid

Only thing I can think of is if the metals used are so different as to affect strength.

Otherwise....You might be a friggen Genius

Could always machine/cleareance the underside of the RC51 tree to make it flat, and use a large steel plate/washer to spread out the load and increase overall strength...a little dowel hole on top to help limit bracket rotation....hmmmm

I've seen it done on a F4i top clamp and it was bent, without sandwiching the material around the mounting holes "NO WHEELIES"

See the reply below yours about the F4i bent clamp ?

If a RC51 clamp was to be used, this is what I would do, having seen the comment about the F4i :

Machine the underside pocket on the riser and deck surfaces, in the area where the bolts would go.
Machine up a piece of aluminum to nest in the now nicely machined pocket.
Do some very careful welding to weld the piece in place.
Drill and tap from the top.

obviously that's the way to do it. The problem is it isn't 919 specific, still needs to be modded and it's around ~$500

I don't think you're going to find anything 919 specific for USD forks on a 919 since they never came that way. Unfortunatly you're stuck either cobbing something together out of parts from a different bike or ponying up for custom billet parts, if it was cheap (or easy) one of the RC51 sets of forks I have would be hanging off the front of mine already.
Maybe track down a set of CB1000R triples, they might be made to work with a minimum of modification.

So what's the issue your seeing with the RC51's upper tree? No drop in the upper so the fork legs would be to short...misalignment of some sort...inability to press in a longer stem.....whatchya seein??

I think I found one that is under $250 and will fork even better that S&P or LSL.

That $500 LSL is for cbr 929/954 and it obviously forks with 919/929 stem and RC51 forks. It will need some additional material on the bottom in order to install 919 headlight bracket as it was machined on the bottom (see pic)



Well here it is, hohey $235 929 triple that has plenty of material on the bottom to accept 919 headlight bracket holes. It also offers the versatility to run handlebars or switch to clip-ons as you wish, thanks to the offset between the top and fork ears

And I do believe with the dropped upper clamps you can run the 929/954 forks

ok, lets sum up this budget rc51 conversion:


rc51 sp2 forks - $350
rc51 320mm rotors - $75
rc51 axle + bearings etc - $50 - $100
machining 919 front wheel to accept rc51 bearings/axle -$65
custom steering stem - $150
929 lower triple -$50
custom upper triple - $250
fender -$30 ????

$1070, not sure about a budget conversion, lol

well, since I already got all part in bold, I will continue with this long term project.
Right now I just will be enjoying my freshly rebuild Ohlins/919 shock and revalved/resprung/rebuild f4i forks

there will be no issues with RC51 triple if built properly. I twill fit perfectly with rc51 forks and it's the way to go if one wishes to use clip-ons. I just think by the time it is set and done for handlebar conversion, one will drop around $200.

So for $250 you'd have a billet upper with multiple handlebar options....not a bad deal for $50 more...it's the $500+ uppers that I think are a bit much, and they don't even give ya the options the hohey ones do....nice find!

If you're looking to keep the three spoke wheels the 929/954 wheel takes RC51 bearings spacers and rotors ands is a dead ringer for the 919 wheel

S&P was made just for 919, unfortunately it's made in Italy, something like $800 and I believe they don't make it anymore.
I almost got cb1000r top triple from UK, wasn't sure if it has the same rake/fork distance as my lower 929 though. Cb1000r is the way to go if you can pick up a complete assembly, thank to opper we know it will fit

I went through all the scenarios mentioned above while doing my front-end project. I started with the 929 lower, 919 stem and was looking for a RC51 upper on ebay but never found one. I was planning to have a machine shop drill the upper clamp, like mentioned above. When I couldn't find a RC51 upper clamp I got the Speigler LSL upper, and then got screwed over by the machininst and no work was ever done. I finally gave up and got the S&P triples, since they were bolt-on and ready to go.
