the 650 motor in the BMW was detuned at BMW's request for relieability. It is common knowledge in the watercraft, and snowmobile industries (two strokes), that Rotax builds more power per cc, in their products than the other brands. The trade off is relieability. Everyone know someone that had this or that, and it lasted forever. I own several Rotax powered toys, but none 4 strokes. I also read somewhere, that the ownership is over half of Rotax to Bomb., but I didn't not think they are the same company. It's researchable, but I'm not that interested!

I must disagree. The Raptor engine and the DS engine are quite different. If you know what mods you are going to do there are a number of us that could tell you which engine is better. (See my post above.)

 

DuneMe, I don't disagree. I believe from a maintenance and general repair, stand point, HoundDog06 will have no problems adapting his skills to repairing and modding a Rotax four stroke. [img]i/expressions/face-icon-small-happy.gif[/img]

 

The rotax DS 650 engine to my understanding is the same as the f650 BMW. Also it is in a detuned state from the BMW. There are hop up componants that can and suposed to be reliable; produce 85hp. This is from people that have the BMW f650s. This was also in one of my magizines. Hope this is of some help.

 

also the ds is also higher than the raptor or the v force,[img]i/expressions/face-icon-small-smile.gif[/img]

WOW... interesting comments here. I'll give a little more to chew on... Rotax rules! Period. I can back up the claim so many ways for so many years of experience in the field of playtoys. Know what? GET THIS!!! (I think I'll post this in a separate thread to the entire Bombardier group just for grins) I was working the Bountiful, Utah parade for the Sheriff's office last year while riding my DS650 Baja and this guy on some wild-looking one-off motorcycle stopped over to chat with me. He said it was a special bike built for the Secret Service. It kinda looked weird is all I knew. Had some BMW appearance to it, but it was just different than anything I've seen. He said that Harley Davidson had sent it to him to test it and send them back his thoughts... I started thinking that this guy was a little bit "off his rocker" at this point. Then he pointed to my DS650 and said "how do you like that, I designed it." I said, uhhhhhhhhhhhhhhhhhhhhhh.... I like it. Thinking to myself, this guy really is WACKED. So I had to confront him, I couldn't take it anymore than a few minutes... I said, what do you mean you designed it? He said, Yes, I designed it for Bombardier, they asked for 3 plans for 3 different versions, and I designed 3 different versions of the bike and they built that one, which I thought was their least likely to build version of the bike because I thought it was too big... Trying to make a long story with this guy short, he REALLY DID design the DS650! I was talking to Frank White that owns and is the top engineer for ATK motorcycles. www.atkusa.com Wow, interesting conversation! This guy wasn't wacked at all, he was telling the truth totally, and what an interesting life he's got. Here's a pic of Frank White Anyway, the moral of this story is what he told me about the ROTAX 650 MOTOR that's in the DS650, and how many other motorcycles he engineers this engine into, so the bike will have the ultimate in reliability etc... Frank engineers for BMW, Harley, Bombardier, and many, MANY other manufacturers that you'd never even think of... and he builds bikes specifically for law enforcement like the Secret Service, FBI, Police, Sheriff, etc. etc. etc... His facility is right next to where I was that day in Bountiful, UT in the neighboring city of Centerville, UT. He basically says ROTAX RULES, but that wasn't news to me, I already knew but his word on this matter tends to be gospel to so many big manufacturers. Interesting, huh?

That's too cool Wizard!! That would be quite a privilage to meet the guy that designed your quad!! WOW MAN!
