WHO USES THE ZTR PRODUCTS CHAIN TENSIONER?

This chain tensioner is used by top riders in motorcross and extreme racing.  We have customers in many more racing environments:  uphill climbers, endurance racing, desert racing, shifter carts, sand rails, dune buggies, etc. 

We designed the ZTR Products Chain Tensioner to keep the chain on your atv or motorcycle in the most rigorous environments.  It is so innovative that we are getting a patent on it!   

Our ZTR Products Chain Tensioner fits on most ATV's with very little to no modification to the ATV.  Please contact us or our distributors for compatability to your particular application.

FEATURES:

The chain tensioner can be mounted in many different ways.  We fabricate springs (two different springs available) that allow the chain tensioner to be assembled in two different ways as shown below:

There are three different chain tensioner rollers available:  420, 520, 620.

DESIGN PROCESS FOR THE ZTR PRODUCTS CHAIN TENSIONER

    What is so important about it?      

    What makes it better than what I can already buy?

Well, since you asked, we will tell you.  We will state our process for developing this exciting new product.

DETERMINE THE PROBLEM:

We found out from racers that they have a problem with their chains popping off of their sprockets.  It has caused lost races and accidents. 

We took a current design that is very standard for racers.  We determined that it needed to be built with closer tolerances to reduce "slop" in the movement of the chain tensioner.  The excessive "slop" in current atv chain tensioners cause the angle of movement of the chain tensioner to change differently than the angle change of the chain (basically, the angles of the chain and tensioner are different and cause the chain to be pushed to the side).  When the chain has a side force applied from a badly manufactured chain tensioner it causes the chain to "pop" off of the sprocket. 

We also determined that the biggest problem is the roller.  If the chain was allowed to move excessively sideways on the roller, then it was more likely to come off of the sprocket.

SOLVE THE PROBLEM:

We developed the special roller geometry by analyzing how the chain reacts when the atv or motorcycle takes jumps.  The roller encapsulates the chain and allows it to only move a specified distance which is customizable by the user.

We have a lot of experience (nearly 70 years of combined experience) in making precision CNC machined parts (What is CNC? ).

A stress analysis was conducted on all of the pieces to ensure that the design is very robust and able to stand up to a harsh environment.

WHO CAN USE IT?

Motocross racers, quad racers, extreme racers, anyone who is tired of their chain coming off of their sprocket.

RESULTS:

Oh, yeah baby!  This thing is awesome!  Sorry, I got a little carried away.  I meant to say, "THIS THING IS BETTER THAN SLICED BREAD!".  Sorry, this isn't very professional. 

This new design performs great.  We at Zero Tolerance Racing Products strive to bring you the best.
