Honda makes their "torque sensing" front differential, Polaris has their electric locking front end, Yamaha and the others have a "locking" differential.

Do any others have any type of "limited slips" in the front of their ATVs?

What does Yamaha (or any other manufactures) use in the front differential of their 4-wd ATVs???

Or are they "open" differentials?

 

I was under the impression that the atvs with 4wd and separate lockers and SRA had a limited slip front w/ the option to lock. While IRS quads like the grizzly had limited slip all around with a locker. Now that I think about it I'm not sure if the locker on the grizz locks all four wheels, if the rears are already locked, or if the locker only effects the fronts...

Now you have me wondering.[img]i/expressions/face-icon-small-confused.gif[/img]

 

The rear on the grizz as with 99% of the quads is a spool (locked solid). The fron on the Grizz is an open face diff with the capability to be locked solid.

 

My buddy has a Grizz, and it is pathetic without a locker! I watched him once with one front wheel on snow and the other on solid ground, and the snow wheel spun like carzy and the other wheel did nothing at all.

 

Most hondas use the sure trac, which uses a mechanical engagement...nothing to wear out, but doesnt lock, but is torque sensing, meaning the tire that needs torque can get it, provided the other side has some resistance. It uses cam pieces and face plates, much like a land rover, in fact its licensed from them.
Bomb uses a visco differential, which is a fluid based diff. The difference in side to side rotation causes the fluid to thicken and transferr power to the tire that has resistance, and works very well.
Yami and kawi and suzi, use clutch plates, for speed sensing differentials. Some are capible of locking, some electrically and others mechanically...but both just tighten the clutch pack for diff lock. Very durable, light steering, and cheap to manufacture, but has the disavantage of sending torque to the tire which has the least amount of traction. However if you have the diff lock option ...its no biggie.

 

Honda's 'torque sensing' front diff is just another FANCY word for LIMITED SLIP and designed to help sell more of their products..I had their fancy torque sensing diff in my 2003 Rincon,and it did NOT work as described by Honda..Many of my riding friends also had it on their Honda's and they also agreed with me.

 

Sound like the Hondas that we ride with. The bad thing is that they are like that all the time because Honda has yet to install a diff lock like the Grizz.

 

If you do have a one wheel spin out with a honda light pressure to the front breaks gets power to both front wheels.

 

thanks hondabuster, do the ones with the clutches use spyder gears to put pressure on the discs to engage them??

 

I believe that it is the same with the Yamaha quads that don't have the diff-lock.
