2012 Yamaha's

[Grimm]

But that's how the OEMs make their money...on the comeback, ie. Idlers, sliders, exhaust donuts, bushings, etc.

http://patft.uspto.gov/netacgi/nph-Pars ... D2=&d=PTXT This is what i'm looing at, maybe this is what you are looking at to, last year at this time some of these things werent on here. I'm looking at the date at the top of the page, when it was put on that site, not the file date witch is older. It might be nothing , but it's fun to look in here, i wish my computer could bring up the images

Boy I see ALOT of patents pointing to a Snow Bike type vehicle, Many them around the same time as the patents that were incorporated into the 2011 Apex (2007 patent date). SO it looks like they prototype atleast 3-4 years in advance. Another site I try to watch is the California EPA site, usually new engines pop-up on there under emissions testing.

A google patent search lets you bring up the drawings. Lots on the snow bike type vehicle for sure. Some of the swing arm type track rear suspension drawings are interesting looking.
Two standouts for me are 1. a patent aimed at reducing the weight/size of tha 4-stroke engine. 2. a patent on a front suspension, ski and track design that allows a conventional layout snowmobile to lean into turns or sidehill like a motorcycle.

I'm hopeing for an EPS Venture with an Apex Motor, or a good looking 2 up seat for the Apex XTX.

I had my little guy (5 years old) out with me on my sled(Venture 4 stroke) today and it was a lot of fun and I can see myself doing a lot more of it, but I want more power.

If the rumors are true and Yamaha stops building sleds soon, then there's no way they will come out with anything to outdoo the competitions sleds. Frankly with already being behind, if they are going to give up on sleds then we've all seen the best they got. I don't ever want to see them give up but kinda get the feeling it may be true.. sucks

behind? what??

 

[low slung]

The next big thing to hit the sleds builders is the EPA clamping down on methane produce by sled engines.Depending on how this plays out,yamaha may be well ahead of the competition.

Track design in that patent is like a snowhawk track, taller lugs in the center. shorter at the sides. Looks like it uses up front susp. travel in the lean. I think it looks like phazer just as a generic snowmobile for parts not covered by the patent.
My bro said he saw a patent for a lightweight, revised cooling system on there last year. That and the patent to drop part of the cylinder bore into the crankcase (shortening and lightening the engine) I like the most out of what I found.
