SP-1 and SP-2 brakes are, respectively, essentially the same as 929 and 954 (in terms of calipers and MCs), the only major difference is the use of 320mm rotors on the RC compared to 330mm rotors on the CBRs. YOu can't go wrong with any of the combinations.

OK so here is something I didn't see, what's the spacing for the rotor on each? My thought process is I'd prefer to keep the stock VTR wheel so they match fr-rr. I would think the axle issue should be solvable with different bearings. But are the rotor spacings different that would negate this? Also are the rotor bolt patterns different where they woudn't be interchangable? I wouldn't think it'd be to hard to put a shim behind the rotor to space them further apart if needed. Though if they are closer together on the RC or CBR that may be an issue.

So y'all think $250 for both forks, upper and lower tripple clamps and the axle of an '00 929 is a good buy? What's the difference between the calipers on the SH vs the 929?

A decent starting point, the 929 have fork springs that are on the weaker side, so if you are on the smaller side it's a match, for me at ~200 pounds, 929 forks would have needed to be re-sprung anyways, so i didn't bother...

The difference in the calipers alone is much, much larger pistons... Combine them with a matching master cylinder and you got stopping power and feel... Combine them with the VTR MC and you stop the bike and keep going yourself, heading for orbit...

I wanted to add that the Second Gen Hayabusa forks will bolt right up to the VTR's frame. The only thing that I really had to make "custom" was all ***** bearings for both the top and bottom half of the triple tree.

They are also 50 mm forks and are considerably (and understandably) larger than the VTR's 41mm. I had to utilize the second gen busa wheel and rotors as well. The turn lock is also wider so it will hit against the top radiator hose but if you read the thread, you would know exactly how to fix that (if you felt froggy enough to). I didn't need to get any kind of custom brake lines or clutch lines because the busa forks (mine did anyway) came with the brake lines intact and in good working order. The clutch line is just long enough to reach the clutch master cylinder so I was able to use the busa's clutch and brake cylinders. Hope this helps anyone out there who is thinking about this swap. Pictures of the front end can be seen from the link in my sig.

At a shop I was working at about a year and a half ago we had a guy set up his sh with a gsx-r 1000 front end, with woodcraft clip ons, sh front wheel. The rest was all gsx-r1000 components. The only issue was you needed spacers for the caliper so it set right with the rotor. (not sure what year the liter front end came off) There may be more to the build that I didn't see but that's to the best of my knowledge all the components.

Umm they are 43mm forks....

50mm outer tubes, 43mm sliders. I think you are both right.

I am in the middle of an SV650S front end swap. The SVRider forum guys have an extensive chart for Suzuki front ends that may be of use for VTR owners wanting measurements and interchangeability of GSXR and BUSA front end parts, wheels, rotors.

Hey JN, got specs on the custom bearings? ID/OD etc? There's a juicy 'busa whole front for sale at a wrecker near my place. Creaming

Something that I see often overlooked is that before a fork swap is the replacement forks often need springs and a revalve. This is certainly the case with Hayabusa forks. The internal valving is crap and the springs are on the soft side for many riders.

Please don't get fooled into thinking straight out of the box the inverted forks will be better. Sure, they are probably better than the stock VTR forks. In most cases doing springs and revalve on your VTR forks will net you better performance than a set of stock inverted forks.

So for someone who rides about 600 miles a year and not extreemly agressive, youre saying reworking stock forks will suffice? im 205 at 5'11'' and my current forks bottom out extreemly easy. its a 98 model and i dont know if previouse owners ever serviced them.
