hi everyone, im new to this forum. i dont actually own a monster at the moment but would like to in the near future. my question is what is the main difference between the S2R and S4R. one is 2 valve and one is 4 valve. i know that the engine for S2R is oil cooled and S4R water cooled right? any suspension changes?

is the price difference actually worth it? how much harder and costly is it to maintain the S4R? which year is the most reliable and that you guys highly recomend? i have been told to get a 06+ monster because it is more reliable and the service interval is longer. is this true? sorry for all the newb questions. been riding for over 4 years now, so this is not my first bike.

thanks a lot.

The newer bikes do have extended service intervals, I don't own either of the big bikes. But I imagine it'll come down to a couple big questions. Can you afford the service on the 4valver? Does the extra girth bother you? Personally I like the 2 valvers looks more. The performance is tempting but not really needed for street. Honestly given the choice all things equal I'd take the S2R. my .02

You didn't say how much experience you have either that could be a BIG deal.  Good luck and honestly, you'll love whatever you get.

07 is the model year with the longer intervals, every 7500 instead of 6000

The main difference between the two machines is obviously the engine. And about 40 horsepower between both of them

The S4R or S4Rs will have better suspension and a lot more carbon goodies than the S2R1K also. The Rs comes with full ohlins, which is something to consider.

That said, I would rather have the aircooled goodness of the S2R1K. In my opinion, it has more than enough power to get you into some serious trouble, maintenance is a lot cheaper, almost half, and honestly, the Testastretta engine in the S4R is a little too much in a bike without fairings, Also it looks cleaner.

Don't get me wrong, the S4R is an absolute beast of a machine, worthy of the name monster, and having one would give way to some serious hooliganism 

My recommendation, test ride both, and whichever makes you feel more comfortable/better, get that one...

if i decide to get a monster it will be used for city riding, weekend twisties, and maybe some commute. i have a r1 right now, so i will do track days with that instead.

If I were already riding an r1 I probably wouldn't opt for a Monster.

How many miles do you have on that R1?

The Rs with the suspension dialed in, and the ducati performance chip, and pipes is just a silly bike.

The growl that comes from that airbox lets you know that you have a beast of a motor that is pissed and whats to run, and the brakes and suspension are amazing. And the amount of roll on power that mill makes is really something to be seen.

The monster is a fun bike to ride, I think pretty damn comfortable and if you have a liter bike to ride like a maniac why not look at a Rs? It certainly won't have the top speed of a liter bike, but it will claw at the ground and accelerate like a bat out of hell to speeds that will cost you your ability to legally ride a motorcycle
