Plus 1...That Evolution is just hideous. Of all the bikes to revamp the cosmetics for. Why choose arguably the best looking bike of all time? It's like a karaoke singer trying to cover Freddie Mercury.
The carbon dream carbon kit "Evoluzione" for 998 looks good ... except the front fairing which is "special" !Plus 1...
Could you expand a bit on what you mean when you say part of the SPS character comes from it's tranny and primary gearing? I'm wondering from the perspective vis a vis standard 996 tranny and gearingI say go for it ... the purists out there have my respect for insisting on OEM for what is largely just a resale value purpose, but for pure seat of the pants joy there's probably more fun in having an SPS with 'improvements', be they asthetic or mechanical ... and in the end if you like what the thing looks like fairing/colour scheme wise, what difference does it make when you are fanging through the twisties.
The SPS character comes from it's cams, tranny and primary gearing.
I'm actually rebuilding my old 996SPS from the ground up right now .... except it's not an sps, it was a 916SP. The engine got changed to SPS specs in 97-99. And, shock horror, I've p/coated the frame silver ... and the engine will be better than a stock sps ... I hope ( it might rev too quick and lose the lazy torque they have, hope not)
I'm still going to call it my SPS though.

Yes, I realize the SPS is quite different, but I'm curious specifically about the tranny and final gear ratios that KiwiEd spoke about, how those two aspects influence the SPS experience vis a vis a standard 996In Europe, the SPS engine come with Titanium internal parts, specific cams, gearing rate. The SPS engine is different that the standart 996.
I chose to keep the 996R over the SPS's. There's no other bike I'd rather have, but I'll tell you first hand: If you were to cover up the speedometers and just ride them back to back, or if there were no dynographs to tell you otherwise, you would swear from the sound and the "feel" that the SPS was faster. It just has a more raucous quality. It's animalistic.
OK, I may be getting this wrong because tbh I don't even know what the later 996 Bipostas were running tranny and gear wise, nor any changes that were made to the later SPS.Yes, I realize the SPS is quite different, but I'm curious specifically about the tranny and final gear ratios that KiwiEd spoke about, how those two aspects influence the SPS experience vis a vis a standard 996
Yep, know what you mean Adam.Ed, I'm with you. It's funny--on September 14th, in a thread about 996R's holding their value, I wrote the following:

Without quoting numbers, which anyone can do by checking comparison data, the 996SPS runs a different ratio primary gearing (NOT final gearing as you have mentioned above) which was actually the same as the 996 Corse engines. The tranny is a close ratio box same as the 748 (which has different primary gearing) and certaintly completely different than the 916's.
I'm assuming here that you know what and where the primary gears are.
So to answer your question, the 'character' that I alluded to, comes from the way the cams deliver the power and the way the gear ratio's work to deliver that power to ground. It was unique to the SPS and worked extremely well with the difference between a 996 Biposta and a 996 SPS being like night and day.
My opinion anyway.
Similar experience with similar bikesYep, know what you mean Adam.
In fact, like you speaking first hand, my race experiences on first my "SPS" engined bike, then on a 1997/8 spec Corse (ex FBF) and then on a 2001 996RS I built ....... the lap times were not that different.
I should clarify that I was just an average club racer with a very modest budget so getting 10/10ths out of the engines was never even remotely on the radar ..... and in reality that meant that it was easier to get max power out of the SPS by tuning it to deliver it's peak power at 10K and thus utilizing all it could give you. On the other hand, to get the max out of the corse engines revving to 12-13K + was needed ... and that's something I refused to do since I was paying for them, so therefore it follows I wasn't utilizing all they could offer.
So, from that perspective, racing the SPS was more satisfying.
In addition, the corse's with their race trannies, are absolute pigs to get of the line (without burning up a clutch every race) where as the sps was brilliant of the line.
Again, all just my opinion.
When I drop the SPS cams in my track bike I'll be able to make a comparison, but there probably won't be any riding until Spring. Close ratio box may be nice, but an SPS powerband is anything but peaky. I don't think wider ratios are going to hurt or change things that much as long as the final drive ratio is adjusted accordingly. Numbers are irrelevant, but look at the shape of this curve, noting the torque above 70 between 6500 and 9000 RPM:Is slotting in a 748 tranny in my 996 along with the SPS cams a recommended step for more of that SPS feel or character?
I realize this is veering a bit from the original post, but people were talking SPS character, I was planning on posting a thread about CR boxes....
