SX 137 thoughts

[upfront719]

I would like to hear from those of you that have ridden the SX long track. Pros/cons??

I already ordered one, but I would still like to get some feedback. I've had all of the other kits so I figured I would try this out. I'm thinking it will be the perfect ride for what we do (75% technical off trail and 25% trails / two-tracks)

I built a 2015 Yamaha YZ450F with a Timbersled 137 SX last year.

It was one of the funnest bikes I had in my fleet for day-to-day hair on fire riding. The 137 SX would allow me to pick up the front end at will to prepair for a creek jump or log crossing, with no effort needed. Usually you have to let the track dig down to create the appropriate angle to jump a log, with this kit, just roll onto the throttle and the front end picks up off the snow allowing you to jump that log. This kit also jumps very well. I enjoyed airing it out this season. You will also find that in the supertight trees you don't ever notice the length, you only notice the awesome traction.

The only drawback to this kit is that on very steep climb exits you have to concentrate on where your weight is. If you are slightly off to the left or right it will try to loop out. It will actually will try to pick the ski off the snow and if your weight is either left or right you will loop that way. None of my other kits have ever done this, so it was something new to learn, but very very manageable.



If this kit would have worked on my 2015 YZ450F, KMS turbo bike I would've been in hog heaven, but unfortunately, you can't have it all in one bike. So I build multiple bikes.

Noticed in your history of bikes that you have done the same thing we have up here in Canada and that is started on the big bore enduro bikes and then transitioned to MX bikes. My thoughts where because we started on TS and then moved to Yeti but it seems to be the trend with TS guys as well. Your thoughts?

Yes, I am transitioning over to: I'm a better rider and don't need electric start as much as I needed it the first few seasons. The 2015 YZ450F with the close ratio transmission, and the low end grunt that pulls out of the hole and comes out the top at 11,500 rpm is so much more fun for an experienced rider. I have no problem trading in my easy button for these advantages. Plus, the realibility of the Yamaha is second to none. I had a ZERO repair winter with all 4 of my Yamaha's. I logged in 50 days on the snow and we put a total of about 240hrs on the machines. Not bad #'s for one of the worst snow seasons on record.

The big bores are fun, just more tractor like, and less hair on fire, branches sticking out of your helmet kind of ride. The high rev limit is what makes a killer snow bike. In my opinion.

Hopefully that helps explain my evolution.

We've been saying it for years and finally people are listening. Toby has it exactly right.... the 450MX race bikes are the best for snowbiking. Any MX bike will give you a snowjob, but the KTM/Husky and YZ 450 motors are tan-fastic. YZ specifically since 2014 and KTM since 2013.
