2009 550 EFI H1 or 2010 450 EFI H1

Which one would you get and why? There is only $100 difference between the two machines at a dealership near me.

Thank you.

I'd go for the '09 550. I don't see much difference between the years so I'd go with the larger displacement. Also, I'm biased as I have a '09 550.

There is an old hot rodders rule of thumb, "No replacement for displacement" Not knowing for sure since i have zero experience with either, I envision easily spending a lot more than a hundred dollars on the 450 just to get close to equal performance to the stock 550H1 which is pretty damn close to the rated HP of the 650H1 because of the EFI
Have a Problem?

Troubleshooting First Steps, An amazing number of problems are cured with just these two items.

1. Make sure your battery is FULLY Charged.
2. Try a new spark plug.

Search threads, Check Pinned Section. Pinned Topics Manual or wiring diagram? Manuals

Improving Search.

Better results when searching for specific information. To find threads where ALL the words, instead of ANY of the words "650H1, Carb, Jetting, Needle Jet, Snorkel" were found...Open up a search window in In the find box type without the quotes "650H1 Carb Jetting Needle Jet Snorkel" & Press return. Find threads, replies or topics by a specific member; just by inserting their user name into the search list; Chances are, your problem is NOT unique and it has been solved many times before.

Are you in a hurry to get an answer?
Use the Google Search Tip

ATV: 2009 550 TRV EFI H1
Love my 09 550. I've had it for over 2 years now with lots of miles on it, runs great. Regular maintenance and it'll do anything for you.

ATV: TRV700H1 XT/550H1
2009 Mileage: 800

I'll have to agree with the general concensus here and say GO FOR THE 550!

The wifey has had one for close to 2 yrs now and 600mls w/o a SINGLE issue or problem.

Just so we're clear.......I DO NOT have an Arctic Cat ATV Addiction..........wellll...YES...yes I do.....

2013 700H1 TRV XT (Mine!!) - 265mls
2009 550H1 EFI (Wifey's) - 990mls
2008 650H1 TRV (gone...but not forgotten) - 2250mls
2009 250Utility 4x2 (was great!! till "The Boy" outgrew it) - 480mls

Considering both have the same towing rating, hauling rating and everything else, I would go for the 450. Unless you are a speed demon it will do everything the 550 will do but at a slightly lighter probably more efficiant manor. Plus nothing wrong with having a year newer bike.
