For 2006 and 2007, there is only one DS650. It weighs 494 pounds. Now if we want to be fair about it, maybe we should compare
similarily priced quads. The Outlaw 525 is $7299, the DS650 is $7199. The Outlaw 525 is 99 pounds lighter than the DS650.

 

Continuing on with our discussion of the engine. The BRP 800 has a bore and stroke of 91mm by 62 mm. According to my calculations, that puts the displacement at 806.5 cc. I had thought that the BRP 800 was basically two 400s. However, the bore and stroke for the 400 is 91mm by 61.5. It appears that the BRP 650 also has a stroke of 62 mm.

Now I am not sure if the stroke is a typo at 62 mm, but if it is not, then the BRP 800 is not legally an ATV in the state of Minnesota. LOL.. question.. is it legal to run the BRP 800 in an ATV race in the state of Minnesota since it is not an ATV???

Although it may limit where you can ride, I guess the guys in Minnesota can always ride their ATV around in their back yard. I would guess there will be a big rush to buy 650 stickers at the ATV dealers in Minnesota.

 

You know, I never understood why people that own other brands come over here and try so hard to convince us that our stuff sucks. If you dont like the DS, or the Outty than go back to the Polaris page or whatever page you desire and tell them all about.

Whats funny to me is how much jealousy came about when the 800 Outlander came out. Just wait till the Renagade and the new 450 come out. They'll be selling tissue's by the truck load.[img]i/expressions/face-icon-small-shocked.gif[/img]

 

According to my calculations, GTX needs to quit posting useless crap!!

 

Thats true, they now only make one model. But if you really want to be fair, the DS is almost a 10 year old design that was intended as a dune, baja racer type quad and not a MX track race quad like the Outlaw/Preditor. I am not sure the best catagory match will be the Oulaw/ preditors vs the other race quads like the coming can-am 450. The ds and outlaw are not really ment for the same type of racing. Now that said if you look at what polaris was building 10 or even 5 years ago, there sport quads were all auto trans and a 250 TB weighed almost as much the DS 650.

As far as your coment about cc of a Outlander 800 being over 800, the numbers you have found somewhere have been rounded up to the next whole number. The actual bore is 90.928 and I seem to recall the actual stroke is something like 61.???? which makes it come out to a true 800. As far as minasota is concerned I think they better get to fixing that law, because the rest of the world is likely going to continue going bigger in the quad cc war. One state in the US is not going to hold up the global market and its hunger for more and more power.

 

This thread is posted "can-am800 vs sportsman800". If you only want to hear about the BRP 800, then change the name of the thread.

My last post was specifically about the 800. It seems to me that it might be important that a BRP 800 does not meet the requirements of an ATV in the state of Minnesota. From the Minnesota Department of natural resources:

"ATVs are motorized, flotation-tired vehicles with at
least three but no more than six low pressure tires, with
an engine displacement of less than 800 cubic centimeters and a
total dry weight of less than 900 pounds. ATVs over 900 pounds
are currently classified as ORVs."

Now comparing a Polaris 800 to a BRP 800.. There are many places you cannot ride the BRP 800 in Minnesota if it in fact has a displacement greater than 800cc. On the other hand, the Polaris 800 is less than 800cc, so you can ride it anywhere an ATV is allowed in Minnesota. Seems to me, a resident of Minnesota might be interested.

 

You need to get your numbers straight. The standard piston size is 90.958. With a minimum 0.0016 inch piston clearance (0.042mm), it is exactly 91mm. Although that piston clearance sounds kinda tight to me. Now if the stroke is 61.5mm, then it is 799.997 cc. However, the stroke apparently is not 61.5 otherwise I would think they would have listed it at 61.5mm just like they listed the 400 at 61.5mm.

Now either BRP has a typo.. or they are easily above 800cc.

 

I believe they have to be registered in Minnesota and since I happen to have a few MSOs to look at I think I can say the the problem has been taken care of. My oldest machine states 800cc as the engine sizes, however my newer ones state 799 cc as the engine size. So problem solved for residents of Minnesota.

 

OMG if it's that big a deal change the sticker to say 650 and shut up!

 

LOL.. so what's the bore and stroke again????? And how did they solve the problem????
