2018 Who knows?
Well as for new 2018 updates or a Snowbike out of the box is any bodies guess, all kinds of roomers and speculation. As for kits today my take from what I've seen and experienced in 7 years of snow bikes.
Score: $ ditch it, $$ ouch, $$$ rideable, $$$$ very good, $$$$$, crem de la crem
Timbersled:
Pros; good progression in kits from year to year and the fact you could upgrade your existing kit. If you hit a hazard and wrinkled a side panel take it off pound it out, or order new one bolt it on. Good stock suspension on all kits, better if upgrade to TSS and/or stock skid shocks and coil overs. Back Country Ski progressed from Widow Maker to acceptable, but change out carbides upgrade attachment bolt. Spindle is good. New track very good, lotsa bite. Do your maintenance, (necessary on all kit manufactures) lotsa chain wax, correct tension on track & chains, grease your zirks all of them! Fit n finish and welds generally good. Still best jumping kit out their just ask Zieg, Hoyer, and Turcotte.
Cons; key way shafts & sprockets on early models. double bearing did not resolve the whole issue of side loading and bearing failures (see CMX for solution), chain drives gotta go bye bye, way to much rolling resistance at low rpm and speed, hello belt and CnC aluminum cogs and fast gear changing. Lighten the load shes a little stout. Brakes are ok but could use a shroud, (initially nothing if frozen) needed by nubies and motoXcross but not steep and deep tree riding as much.
Good updates, great performer, good value & solid build for the money. Score: $$$$
YETI:
Pros; Looks are always a personal thing, but the Yetis actually starting to grow on me. Having said that all carbon fibre tunnel, titanium shaft and fittings all over the place, CnC aluminuim, belt drive, best ski in the industry, very good track, suspension up grade with new mono shock, super light, what more can I say. This is a very progressive kit with modern materials, engineering, and very good to excellent fit and finish. I have not crushed a Yeti spindle yet, so I don't know if it fails as it should before my forks do?$$$. How does it perform you ask, ski tracks very well on packed trail & very good control, good floatation in POW, good bite on crust and side hilling. This is a premium kit that has very good to excellent performance in all conditions. I have not ridden one with the new mono shock, so jury out until I do, suspension is only second to dependability then power, I know the Snowflakes will disagree with me on that one, wait until they have to walk out in 4' of POW, in the dark, 12 below 0 and 10 miles to the truck!
Cons: As with TS, Yeti has done a good job of improving their end product by listening to their customer base and making improvements from year to year, i.e. Wider belt and cog drives, better tunnel accessories and attachments for gas can, cargo, track, suspension mods, etc. these are no longer cons but improvements. The only con I have is the tunnel, one piece, could be stiffer & more robust. I have a bad habit of hitting sheet & breaking things on Snow bikes, other wise 5$.
Very good engineering, performance, materials and inovation.
Score: $$$$
CMX
Pros: Now here is a kit the minute I laid my eyes on it I knew that they had lots of experience in building skids and improved the good and dumped the so/so from the competitors. Well thought out kit, good tunnel, side panels, rails, track, suspension, etc. The home run was the drive shaft going full length across the other side of the bike and mounting the belt drive (Jack shaft) on the right side of the bike, I will some it up in this way, balance, no side loading bearings, efficient belt drive, low rolling resistance, ask Toby does this thing fly? For weight I put it between the TS and Yeti.
Cons: Now I may not be the best person to point out any short comings on this kit, because in fairness I have not thrown a leg over it yet, as Toby mentioned he will comment in time so maybe other riders will chime in. So on that note I will base my score on my perception, mechanical engineering knowledge, fabricating skill, and snowbike riding experience and adjust my score accordingly once I have ridden it hard and put it away very wet, as I am itchin to ride it. The only con I could have said was thank god you dumped the 2 ganger ski and went YETI!
Looks like a very well thought out design and quality workmanship and materials.
Score: $$$$
Camso to come!
