Yamaha R1 mountain horse

You've probably seen videos on youtube of this snowbike.
It's probably very heavy and not as nimble in the trees as pure dirt bikes but at the same time lots of power!
A show off snow bike or something to consider for pure hill climbing?
I would like to see this bike in some of the upcoming hillclimb movies.
Does anyone have informaton of this build?

I dont know anything about that build, but I love it ! Yamaha baby lol

Wow! I love the sound of HP!

80 degree boys! we are doing vertical next

I've seen the vids.. I want one!!! Clearly the commentator doesn't know what the true angle is, although it looks ridiculously steep!

I'd be more curious to see how it fit in the dirt bike frame and what mods had to be done to accommodate it.

Was only a matter of time. Dirt bike hillclimbers have been stuffing street bike engines into dirt bike chassis for open classes for decades. Major chassis surgery and fab required. Simplified explanation, basically cut the frame in half mount front half to front of engine, rear half to rear, then fab in what is missing in middle. Very cool!!

Now just throw an Apex turbo kit on it and have 250-300hp.

My first thought was "a turbo + 174x3 and go see what it could climb!" Would be a pig to ride anywhere but straight up though.

That would be called the Casket Filler Special!

One of the great things about the "snow Bike" it is new to the extent that you can build something that has not been done yet. So I saw this the other day and thought that it might be two heavy... but for hill climbs this might be the ticket.

A twin CR 500 Banshee based engine in a newer MX bike frame.
with twin smartcarb's and a two into one exhaust.


Banshee engines are pretty cheap nowadays and I used to ride a Banshee in the mountains in Kodiak Ak in the spring time snow( when the snow is hard enough to walk on) in the early 90's. Modded snowmobile power without boost or a CVT to rob power. Of course you have the weight and need to haul extra fuel etc, etc, so maybe the turbo one lung 4T is the way to go.

Am I the only one who sees these vids as a WAKE UP CALL !!!!! Sidehilling across a slope that obviously slides as evidenced by the destroyed trees below him. Not to mention the terrain trap at the bottom. If he cuts off that slope with his sidehill manoeuvre, a turbo Apex engine wouldn't have enough power to even begin to help him.
Hate to be a downer but we need to be smart about what we are doing and where we are doing it

All slopes slide. And I don't see any destroyed trees? Were you there? did you dig a pit? easy to second guess. If you can tell what will slide, you need to do avalanche forecasts. Even the pros can't say if/when a particular slope will slide.

Wonder how a phazer motor would work in snow bike kit? I think they were 80 hp stock with some boost 125-130 hp I know they werent too reliable on big boost but i think it will hold up alot better than a 450 motor on boost

 

[Little Eddy]

UpHigh …. You just don't want to see …. try digging one of your ride partners out of something like this and you will see things in different light. I have, and until you do you will never understand so rather than being a smart a$$ about it why not just leave it be

Yes, that slope will slide many times over the course of a winter, and some of those avalanches will be triggered by much less than a bike crossing the slope. There are also many, many days that it will be perfectly safe to carve the hell out of that sucker.

If anyone reading this and riding slopes greater than 10 degrees hasn't taken an avalanche safety course, sign up for one now!

I think any kind of snowmobile engine will be difficult to fit in a snowbike.
Engine and clutch package will even be wider than an inline four.

Not being a smarta$$. Asking what you see that I don't. Don't see broken trees or a terrain trap(can't see past trees in the foreground.) Have taken several avy courses. You aren't the only one who has seen or been in an avy. You aren't the only one who has some knowledge and experience. And giving me a bad post rating really doesn't mean much.

I was wondering the same thing the other day.

 

[griffin86]

I wanted to build a KTM 990 engine, turbo it and put it in a carbon fibre/kevlar chassis. No time for that though.

146" track, 2.5" paddles.


One day... one day...

I thought that every snowbiker look at this forum. No relevant replies? Does anyone have any information what this build was about? I know It's heavy but poweful. It would'nt go trough the trees but how is it to ride? Is this a buld that someone ride today?
Can'nt drop the idea of putting a 190 hp BMW1000RR engine into a dirt bike chassie.
A show off build but powerful, no doubt about that...
Think of this as a Turboapex snowbike
