Even if you can double the HP with the turbo, its going to be similar in power and weight as most stock sleds. It'll be a handle full in tight tree riding. The more we push the snow bike envelope, the better the sport will be. Still an awesome project Id love to see and ride.

I haven't ridden a sled as heavy as this bike since 2007 (anyone explain how this could be less than 460 please, I'd love to be wrong...) I can't imagine having any interest in dealing with this thing.

It would be fun in certain situations for sure, but not the kind of fun I'd be looking for really.

Just for reference:

2015 Yamaha YZ450F, 2016 Timbersled ST, KMS turbo with a full tank of fuel.

2015 Yamaha YZ450F, 2015 Timbersled SX137, full of fuel.

Wow on the complete snowbike weight and thanks for doing it. I was going to weigh mine once it's all together. So if there is more than 100lbs more in the FZ07 that puts that snowbike over 450lbs. Holds more gas but the yeti weighs less.

I have no interest in a gear jamming one ski but since the majority are so content on seeing the wheels of progress go backwards and eventually come back around to a turn key machine I have no choice but to comment on this .

I think this FZ is a step in that direction . Comfort for long hauls will be a hundred times better not to mention distance traveled . Even with a turbo one would think longevity would be in it's favor etc , etc .

One very important factor that for some reason is as obvious as the photos that are posted is the balance of the dirt bike kits . They suck , the snowmobile industry has spent millions of dollars balancing machines and than along comes the bike kits .

It would be nice to see how this machine balances out ?

Thanks for posting those weights. What do you think your YZ450 with 2016 SX120 weighs?

 

[tillbuilt]

Just in raw #'s the 2016 SX 120 is 17 lbs. lighter than the 2015 SX 137 so I am going to estamate 309 lbs.

Thanks for posting those weights. What do you think your YZ450 with 2016 SX120 weighs?

Cant wait to see this thing climb!!

It's clear you don't like the 450mx bike/timbersled/yeti solution as much as a Hawk, but you have to admit that they get around very well and weigh a lot less than a Hawk did. That's a big part of the fun - they are so much lighter than other solutions, allowing access into areas that were once not that rideable, PLUS they are still a dirt bike when it comes summer time. Pretty neat even if they aren't perfect.

What i don't see is how a street bike that weighs 150+ lbs more than a dirt bike would be a better solution than 450 single cylinder (that being said, in the right conditions this FZ turbo would be a beast!)

If there is an ideal solution, a new thread started by you would be a great place for some excellent discuss on the matter.

I disagree with Hawkster. Just because you see a snow bike hanging unevenly from its handle bars doesn't mean the machine isn't balance properly for handling. I've yet to see any evidence of anyone riding a snow hawk as extreme as the stuff we are seeing in snow bike videos. But maybe I'm wrong. Maybe a snow hawk is a superior machine. The next I see one on the hill I'll will ask the guy if I can take it for a rip.

Thats because nobody with a sled can keep up with these guys to film them

Here is the weight. Converted to lbs it is about 410 lbs. it is not full of gas but has a few ltrs.
The horsepower target is 130-150. The engine makes plenty of torque in the low and midrange and the turbo will only help that.
It is not light by bike standards but should turn the track harder than a stock 800 sled.
This is mostly speculation of course and will have to wait until it hits the hills to get the real story.

 

[Hawkster]

Is it balancing on the scale ? In front of or behind the pegs ?

You'll be running what a stock Yammy triple is running minus quite a few pounds . If this has any where near the torque pull they have your biggest problem will be keeping the skid under you .

There are a few of us that have speculated what a triple four stroke would be like in one of our rides and have all came to the same conclusion , insane .

This is kind of like opening the door to the super bike world , many champion riders came from the dirt bike but I'm not aware of any super bike riders crossing over to the dirt bike world .

This isn't the first set up but it's got to be one of the nicest . It's definitely a step in the right direction for some .

The build looks so sweet and clean !! Cant wait to booooooyassst it up something in december !! Any suggestions what chute should be its maiden voyage ?

That is really awesome. Its about 100lbs lighter RTR than the lightest stock sled right now which is the Pro 155 with the 2.6 track. So taking off that bike parts and adding the Yeti added no weight to the machine? Im just basing that off the published dry weight for the bike of just shy of 400lbs.

Link to the RTR polaris weight for those interested.

Gixxer with claimed stock 180hp and a track kit. Power wise this is the highmark to beat as of know.

So my ? Is would you do a 55' jump with any of these big bikes? On dirt or snow, can they handle it? Just something like this vid. http://youtu.be/2w9H3he4jAw

Where's the pics of this build?

 

[J&L Snowhawk]

I have most of my build on BCR snowhawk section. Or face book one ski riders support group.

If you take any bike with any kit bolted on, divide it's overall length by 2 and slung it at that point of equal halfs and suspended it, is that what u are refering (meaning) to as "balances out" ? Because if it is, then u are right, u are going to be hard pressed to find one. I do not believe Hawks would either. Litre bikes/multi cylinders with a Yeti attached actually balance out better, if by that definition than dirt bikes and TS attached, as the former is heavier in the front lighter in the rear. If your track, tunnel, skid assembly all in is longer then obviously you're shifting more wt. aft. Snowbike, Hawk or sled.

The big variable factor is you have to introduce the rider onto the snowbike to go anywhere, The rider plays the biggest role in the balance like any bike (Hawk or sled), the position of the rider dictates the balance once it's moving, body english as the palmies call it. I agree a balance point is a good baseline. Is the ideal balance point as close to the overall center or would it be better at the foot pegs, as this is where the variable rider weight goes fore and aft, side to side?
