They are different....personally...I like the regular Monsters better than the S2R's...my 01 Monster 900ie is just the ticket...though a 1000 DS motor would be a bit better in some regards...for me...Monsters are about individuality...and the regular Monsters seem to be able to take on many different types of persona based on needs,wants,and desires as well as personal style...mine for example has dirtbike bars with bark buster type handguards and ATV covers to deflect wind for the winter time cold...and I have a Ventura Rack on the back for loading crap and hauling....I have hooked bungee nets full of stuff onto that rack or taken and put on the Spada45 bag and loaded it with clothing and gone on my way!...I ride mine a little bit more like a SuperMoto but not really and love to have fun with it!.....the S2R's seem to make it harder with the upswept exhaust because the space tolerances are closer...it can be done...but it is harder in certain ways....also...to me...the S2R's look very trick and sweet with that Single Sided Swingarm and big exposed Marchesini 5 spoke wheel...but then it gets to a point somewhat when you'll see a group of S2R's and it is like looking at a bunch of 998's....a little repetative....little modifications here or there....but usually nothing blatent that stands out.....looks at the pictures from Gary Eagan's multiple cities of the Monster Challange and you'll see what I mean about owners giving more persona to non S2R's versus S2R's and S4R's....but that is my opinion....Uif it were me...I'd go for the '04 and see if you can negotiate a deal on pricing for the up and coming 12K service kinda like you would for the 600 mile service if it was a new bike...but that is apon you to figure out for yourself!....plus the '04 is already broken in!ddicosmo said:I'm looking at a 2004 Monster 1000S for around 6k with 5k miles. I'm debating whether I should go ahead and get this used one or buy a new one like the S2. In your opinion, is the 04 1000S a good bike? Is it better than the S2 800?
