like an s4rs?
More a home-brewed 888 look-alike with silly power. 888's (and even 851's) are as rare as hens teeth and are expensive. Later monsters have chassis based on the ST2 or something. In doing further research (851and888 forum...) it seems that there might be one or two of these in the world....like an s4rs?
At this point in time I've got nothing of any donor bike - just a sudden lust for a 888 SP4. So anything to make it easier is good, but keeping the look of the 888 and roughly period looking things on it where possible. Like a restomod. 1198 and as much 1198 engine stuff that can go on. forged alu wheels from a 999, Ohlins forks with axial calipers (!)....there's a few st4s dressed up as 851/888, and marvin has an s4rs engine in his 851, plus there's a couple of 1098 engined ones around.
if you specifically want to use an early m900 frame then you need to modify the cross member in front of the vertical head to be a v shape like any of the 4v one, and add radiator mounts. the st based 4v frame from 2001 s4 onwards would be a better starting point. frame is stronger and already made to suit the 4v engine.
Unsure at the moment but would be nice to 888 it.
The holy grail would be an 888 SP4 or SP5 frame with a 1098R engine. The 888 chassis with a 1200 Multi or Diavel would even be a quick bike. Is the conversion of the testa evo cases to run the swingarm bearings troublesome?Several people have also built 1098/1198 versions, but those are a ton more work--you have big issues to resolve with the airbox, throttle bodies, exhausts, and on and on. BUT...once you solve all those and add late model Panigale electronics you've got a beastly ride with really nice traction control. Find the one from Biggelaar Performance.
Sorry, I was rambling and forgot to elaborate on the 888 SP4 frame thing. We have this scheme in Australia where you can create an Individually Constructed Vehicle (ICV). I'd seen that Pierobin make three types of 888 frames (888 bip, 888S and SBK - 888 Archivi : Pierobon Frames - frames and accessories for motorcycle). So I have the (expensive) option of going down the ICV path as that can use a new frame. The VIN number is done via the engineer who inspects the vehicle. But I'd end up with an 888 frame and rocker rear suspension. Being late at night I'd been seeing SBK as SP4...... blah. Anyway, it seems there's no shortage of wrecked 1098's 1198's, 1200 Multis and Diavels here and that'd be the source of the engine, injection, electrics, switchgear...There's no reason to use an SP frame. It's not TIG welded or braced like the corse frames, has no performance benefits, and you would actually be hurting the value of an SP4 or SPS.
Get a normal, genuine 851 or 888 frame. If you want to be able to enjoy the bike in a reasonable timeline, use a desmoquattro. BTW, even without a big bore you can make a 996 run with a standard 1098 (see dyno) and it will still be cheaper than all the one-off stuff you would need for the testastretta.
What sort of mods do you think would be necessary?A 1098 or 1198 engined 888 chassis would be fun, frame mods would be necessary, and a removable cross brace like the SP and Corsa frames would almost be a necessity.
What sort of mods do you think would be necessary?
And just for the sake of discussion, would a carbon airbox like on the 916SP's stiffen things up? Would you be able to use the fuel tank as the airbox cover?
