Also, regarding the digressive rate in the final inches of travel on the Pro-Action, does that mean Polaris is actually correct in their marketing that the Pro-Ride rear is the first truely progressive rear skid? I had been thinking BS since Ski-doo marketed their skids as progressive back in the mid-80's on the PRS chassis. Now I'm wondering? <em>Hey Scott, I'm not the expert on this but I have learned a few things. Consider the nature of the beast. When the suspension system is contained within the track it must fold into itself as the stroke is compressed By the time you have used up all the travel there is no real estate left for the hardware to live regardless of the geometry and layout. It seems to me that by moving the linkages outside of the skidframe, it allows the engineers the room required to have the angles yield a progressive rate (more mechanical advantage against the force as stroke decreases). As far as Polaris being the first, hmmm looks an awfully lot like a glorified SnowSport to me ;-)</em> Chris,

You haven't mentioned it yet, but did you feel the motor met expectations? I believe the Viper HP ratings were closer to the 600's, rather than the 700 twins of the other OEM's. I never owned a Viper, but looking from the cheap seats, it seemed that the interweb buzz was more about power (lack of) than how stiff it was sprung. Actual owners and their lumbar vertebrae may say otherwise! Very interesting. You haven’t mentioned it yet, but did you feel the motor met expectations?

It answers all the questions I've had concerning the race sleds during that time. It goes to show that it's never as easy as it seems(from the consumer perspective). Thanks. Excellent story. It answers all the questions I’ve had concerning the race sleds during that time.

It goes to show that it’s never as easy as it seems(from the consumer perspective).

Thanks.

Oh, what a sled it would have become without the problems of the consumer version of the mono.... Shame. I´m glad that the mono did come available. It´s great. Needs more durability, but it´s still a great suspension with the E-öhlins. The Viper engine is still one of the nicest triples around. It´s smooth, powerful and has the best sound of the triples (sorry, can´t beat the ole quad under the Vmax-4 hood though). You guys still have any parts of the long travel front ? I could use some on our project here.... Keep up the good work CR! Ike Great reading once again Chris! Oh, what a sled it would have become without the problems of the consumer version of the mono….
