Is the S4RS the Greatest Monster Ever Built?

[Speeddog]

If I'm not mistaken, an S4 shares the same engine, swingarm pivot and frame and can thus be "S4r 'd" fairly easily,  no?

S4R'd with appropriate engine swap, a bit of welding required.

S4Rs'd or S4Rt'd, engine and a bunch of parts, some welding required.

taking my S4 to the track this weekend and i'll post a video .. She's been to the track before, actually my first track day about 6 years ago or so. S4rs.... I'll keep an eye out and hope to see one at the track.

Did all the S4 bikes come with the 916 engine?

S4Rs has 998 motor. There is a thread here somewhere that discusses the differences between those models. I actually thought the S2R1000 was a more impressive bike, except for the Plastic Tank. I'm still pretty happy with my M900, but the new 821 may be a better bike than the S4Rs, except for the looks of the plumbing on left side. The 1200 is overkill IMHO, so is my Diavel for that matter. - Gene

The S4Rs has 998 motor, Ohlins and dry clutch, but the plastic tank, the only downside to that bike.

1200s is missing the dry clutch and the right side is a bit rough, but it's definitely growing on me.

S4RS vs. 821 --- how would you define the 821 as "better" ?

[twolanefun]

Maintenance schedule for starters, electronics, that sound is pretty darn good, and HP is more than enough. - Gene

Thanks man!!!

the S4r is no slouch either and put in a lightweight flywheel and vroom vroom.  METAL TANK PEOPLE, METAL.

Actually the maintenance schedule difference is nothing more than the stroke of a marketing pen.  There is nothing so intrinsically different between the engines that you couldn't maintain the S4Rs on the same schedule. By the same extension you'd likely be better off maintaining the 821 along the schedule of the earlier models. Either way would work. I would say the same about the electronics unless of course you are talking about all the various choices of maps, etc. ABS and whatnot. Then again the 821 really doesn't need all that stuff, really, but the marketing people like to add it on. As for sound and HP. Highly subjective there. Some people like/want more than others and nothing wrong with that either way too.

Hey Quomom: what brand is your carbon seat cowl, or is it OE?

[Qomomoko]

not sure...

my friend/mechanic who helped me let my bike dropped and tore the seat and my beautiful red seat cowls so he go me this CF seat cowl. I still prefer my red one and keep looking for one to get...

I"ll see if there are marking on it to let you know the make.
