I'm kind of curious how many are going with the 153" over the 162" (on non-boosted sleds). I know it depends on geographical area (wet snow or bottomless powder) and if a rider does more tree riding and cross-fall line riding vs. straightline climbing, etc. but how about beginner riders, friends-sleds, or less aggressive guys or gals? What is the right answer there?
My girlfriend was getting pretty tired of wrestling around her Apex 162" and would smile every time she hopped on friends 153" two-strokes. Every year she rides better and better and she has really advanced again this year and by the end of the season, wasn't really as concerned about switching sleds. She's ridden a Nytro, too. Her technique is getting great, but since she is only 130lbs and has one problematic shoulder (separation a couple years ago) and doesn't really get aggressive as the average guy rider, it's a fine line between providing enough flotation to get stuck less but still being able to sidehill and turn the sled. She is improving greatly, but is really held back by the sled at this point which is obvious when I see her hop on 2 stroke 153 sleds and ride so much more confidently. Long story on why she is on a Apex but is there now and wants to stay on a 4 stroke if possible, which I agree with.
So, back to the Viper. The Viper MTX 153" looks like it might be a good fit, but I'm just a tad concerned with less flotation of the 153", however, they are so much lighter than an Apex, maybe a 153" will float it like a 162 on the Apex (and minus all the front end biased weight). She'd like to stick with the four strokes for many reasons; power delivery, mileage, lack of smell, reliablilty, etc. Granted some newer 2 strokes hit some of those marks, but never having to worry about the engine popping while we are out riding is our number 1. Often times it's just her and I riding and I'm on a snowbike, so wouldn't be able to pull out a sled and riding out two-up on the bike would be tricky (though doable).
So not being able to take a new viper for a spin, it's hard to say if the 153" track length benefits (more maneuverable and yes, cheaper) will outweigh the cons (less flotation, etc.). With a twostroke, I don't think I'd hesitate to go with the 153", but with the bit of extra weight, I'm on the fence. I just don't want anything that will get stuck more than her current ride (Apex 162")..but maybe that isn't saying much. Ha.
Opinions on Viper track lengths?
