I am looking for a atv - 400 to 500cc - selectible 2wd 4wd - front diff lock. I know that Honda is out because no front diff lock. Any input on your experience would be helpful. Thanks

 

CanAm makes a 400 and 500cc automatic tranny machine with Visco-Lock which engages when the front tires aren't moving as fast as the backs. Polaris has a Sportsman 400 automatic (really a 450) which is a midsize and the 500 (also an automatic). It's system features AWD that, when selected, engages when the fronts aren't going the same speed as the rears. It's seamless. Works effortlessly. Suzuki has the King Quad in 400, 450, and 500cc. Suzuki offers these with foot shift (semi-auto transmission) and automatic. You can also get the 500 with power steering. Yamaha has the 350 Big Bear and the 450 Grizzly. Polaris and Yamaha have 550 machines with power steering. I don't know much about Arctic Cats. Kawasaki does not have a 400-500 class machine. Some of these machines are solid rear axle some are IRS. CanAm makes a sporty model in 500cc called the Renegade. Polaris has a sporty Scrambler 500 and Yamaha has a Wolverine 450.

 

+1 for the Yamaha 550 Grizz!

 

Every 4x4 400-500 made has selectable 2wd/4wd and most have diff lock except for Polaris and Can AM because they use different AWD system and with Honda you just add a $400 aftermarket diff locker to it.

400ho sportsman
450 Grizzly
400 outlander
450 King Quad
350 grizzly even has diff lock and IRS now.

I think all Arctic Cats and Kawasaki's have diff lock now.

 

i have a jianshe (or a tank sports) brand atv. its a 400 4x4. it is a yamaha 400 4x4 copy. it dosnt have frount diff lock. but it dosnt really matter i could not get this to think about bogging out in any mud or rivers i brought it through. so far i have repaced the clutch, reverse switch and throttle. clutch was just worn i bout it used 2006 model. and my friend flipped it and broke the throttle thumb and the reverse lever. it has a pull start also. nice touch.
