Polaris 550 XP Improvements

Question:

Dear Motorhead:

First off, Dirt Trax is the best ATV show on TV and meeting you guys at Brimstone was a blast.

I own an 09 Polaris 550 XP and it’s been a great ATV. I watched the testing of the XP on your show and you said that there was an improvement in 2010.

I didn’t catch what that improvement was. If it’s something that can be fixed before I go to Utah in the summer please advise.

Thanks,

Luther

Thanks for the kind words!

Our reference was to the over-all refinements made to the 550 in its second year of production. The vibration issues – particularly at idle – have been settled substantially – we suspect a different durometer motor mount was used and other drivability issues including plug fouling have been rectified.

It is a great ATV in any form, but it has been made even better in its subsequent years of production.

2011 ARCTIC CAT XC450I

0

This cool looking sport “crossover” is powered by the same 433cc EFI single as the Arctic Cat 425 sport-ute.

Power is filtered through a Duramatic CVT with built-in engine braking, selectable 4WD and even hi-lo range.

Because it’s designed to do different things than a sport-ute, the 450I is more stripped down in appearance, sans racks and much of the bodywork you’d see on most 4WD ATVs.

The stance is a bit wider and cool looking aluminum wheels come with the package. There’s a big bush bar on the front and ground clearance is a more than adequate 10-inches front and rear.

There’s also different gearing used here to produce power more in line with what sport ATV riders want.

Suspension duties are handled by dual A-arms front and rear and 5-way preload adjustable shocks.

We felt the ride quality was very good for an ATV in this price range and there’s lots of extra equipment like A-arm protectors, dual taillights and back-up lights and aggressive Maxxis tires for increased traction.

This ATV is a great competitor for 4WD Yamaha’s Wolverine and Can-Am’s 500 Renegade. Could be fun to compare them.

Polaris RZR XP 900 Blows the Lid Off

0

As if the Polaris RZR and RZR-S hadn’t made a big enough impression in the side by side marketplace, the boys in Minnesota have created even more cold sweats for the competition with the intro of the new RZR XP 900.

This new-generation Razor is powered by an expanded version of the fuel-injected XP 850 ATV mill with displacement bumped up to 875ccs.

This engine is a 180-degree firing DOHC twin mounted transversely in like fashion to Polaris’ XP ATVs.

Polaris claims this new powerplant makes an amazing 88-horsepower – certainly top-of-the heap power for any 4-wheeler…in any class.

We can’t help but think this mill is a direct response to Arctic Cat and Can-Am’s brags about having the most power in the SxS market with their 1000cc powered Prowlers and Commanders.

For Polaris, this engine in this chassis is without doubt the most volatile combination money can buy without going to the aftermarket.

2010 Winning Year for Can-Am Racers

0

As the new year begins, Can-Am ATV racers – both pro and amateur – can reflect on a successful 2010. Last season, Can-Am ATV racers took home nearly 40 pro and amateur championships across North America.

Chris Bithell gave the Can-Am DS 450 an overall victory at the Yadkinville GNCC and finished fourth overall in the XC1 Pro-class championship. His teammate, Adam McGill, finished third in the Pro-class points standings and was on the overall podium for eight of the 13 rounds of racing. Lexie Coulter raced her DS 450 in the Women’s class and started the season with a win at the Florida opener; she finished fourth in her class.

Team BCS Performance had one goal at the beginning of the NEATV-MX race season: deliver Cody Miller a Pro-class championship. It did that, and added a Pro-Am class championship for Miller, too. The Can-Am DS 450 racer took both of the top series championships and celebrated at the season finale in Maine.

Can-Am X-Team Program racers also had an extremely successful 2010, bringing home 10 championships for BRP. Cole Henry and Chase Henry of Virginia delivered BRP its first AMA ATV MX National championships. Cole took the Production A championship on his Can-Am DS 450 X mx, while his brother Chase secured the 4-Stroke B championship.

For cross country racing in Quebec, Canada; Amelie Lavallee piloted her DS 450 to the FMSQ Pro-Am class championship.

In Texas, X-Team racer Hunter Miller cleaned up in the TQRA and TORN series Pro-class championships. Miller raced his DS 450 to the Open Expert and Pro-Am championships in TQRA, while he also took the Pro championship in the TORN series.

The Can-Am DS 450 Amateur Racer Support Program also produced multiple championships. At last count, 12 amateur ATV racing championships were won on DS 450 ATVs purchased through the program. In the NEATV-MX series, five championships were won by participants of the program. They were: Roy Lampron (25+ Open and 30+ A), Mark Gehring (Production A), Brian Cochrane (Production B) and Mike Troiano (4-Stroke B).

GNCC racing saw Josh Davis win the 24+ C class, while WORCS racer Mike Hrubetz won the 40+ C class championship. OMA series racer Fred Mudd took the 30+ class on his DS 450 in cross-country racing, and in the PAMX series, Rocky Anderson won the Open A class title. In Canada’s CMRC Quebec motocross series, Jean-Sébastien Côté won the Intermediate-class championship.

Honest Opinion of The Brute Force

0

Question:

Dear Motorhead:

I’m thinking about geting a 2009 Brute Force 750 NRA edition. Some guys I work with say the BF had problems with the u-joints going out and the belts messing up. Have you heard of or experinced these problems?

Mind you, I’ve also seen how my firends abuse their trucks and am not surprised that they have problems with their ATVs.

Thanks,

Jason

Reply:

Thanks for your email!

We haven’t tested a Brute Force for about a year, but they haven’t changed at all since then.

My experience with the BF is that its a very solid ATV. We didn’t ever experience any belt issues, but, if you abuse your ATV and don’t pay attention to what your driveline is doing, you will burn belts and bush CV joints on any ATV no matter what brand it is.

We’ve certainly spun a number of CV joints on our ATVs and almost without exception it always happens when we’re stuck in the mud and the 4X4 is working hard to turn the wheels.

Eventually under these conditions as the wheels are searching for traction, a CV joint will snap. This is not a problem with just Kawasaki or the Brute Force in particular, its the same with all ATVs and I would suspect putting your buddies on any ATV would result in the same problems.

Thanks,

Luke Lester

What Does The “R” in 800R Stand For?

Question:

Dear Motorhead:

What does the R in 800R stand for? I have asked several people at shows from BRP without a clear answer. My guess would be that it might have been a project code during development of this 800 at Rotax.

Just curious,

Gus

Reply:

Thanks for your email!

I am assuming you are asking about the Rotax 80 degree Vee twin engine used in the Can-Am Outlander, Renegade and Commander?

Rotax has two 800R engines. One is a 2-stroke snowmobile powerplant and the other is a 4-stroke ATV/SXS engine.

In the case of the ATV/SXS mill the “R” designation was added two model years ago to the pre-existing 800 Vee twin as a result of a “tune-up” that netted a significant increase in peak HP, torque enhancements and better economy.

In the case of the Series III Rotax 800 2-stroke the “R” was added for similar reasons – to delineate the engine in a tuned-up version that recently became the first Direct Injection (DI) 2 stroke snowmobile powerplant in the business.

I think it safe to say “R” is the new “X” when it comes to enhanced engine performance from Rotax.

Is An Outlaw with IRS Fit For The Track?

0

Question:

Dear Motorhead:

I watched a recent episode of Dirt Trax about the Polaris Outlaw IRS. You said it was a great ATV for trails but you wouldn’t see it on a motocross track and I was wondering why?

I enjoy weekend trail riding. At 46 I’m wondering what you might recommend for some light racing for us older guys who still have to go back to work on Mondays – Something like a sport class with moderate skill levels.

Thanks,

Mike

Reply:

Hey Mike
Thanks for your question. It is a good one. The problem with the Outlaw IRS is that the rear end is really quite soft. Which is why its such a great trail ATV.

However, it tends to jump VERY nose high. The rear end doesn’t have enough rebound to kick the back up off the lip of a jump. Its not that it can’t be jumped, its just not as good as a track-specific pure sport ATV.

Furthermore, the extra weight will be noticeable on a moto track as will the body roll. On the trail, these traits aren’t a problem. but on a track they tend to be much more pronounced.

If you are looking to do some light racing I suggest picking up a used motocross ATV. A Yamaha YFZ 450 would be great and sometimes you can score a good deal on one.

I suggest staying away from modified ATVs as reliability can be questionable

If you want to have an ATV for trail riding and a bit of motocross you could get a Polaris Outlaw 525 IRS and try stiffening up the rear shocks a lot. That may help with the nose high jumping and body roll in the corners.

Hoep this helps,
