What the Best Bike For a Tibersled Kit

These are also the reasons I am reluctant to go to a 4. I'd rather do the rebuild more often and it be cheaper and take less time.
 
Yes ,,,rebuild my top end on my 300,,, lets see a piston,rings,, a set of gaskets and mabe a fresh hone, as aposed to valves ,valve seats cam chain piston and rings,gaskets ,,,big head labor,!!! I cringe at the thought of a head problem with my 4 stroke! i wont be fixing that engine in the trailer!"

But you don't have to do it to 4 strokes often if ever. I have ridden 4 strokes my entire life. I am 37 now I have had some with massive amount of miles on them and never once had to rebuild one. In fact I have a friend that has a Yamaha sled with that R1 4 stroke engine 15k on sled and it still runs perfect. I am sure there are exceptions to every rule but I don't get the line of thinking.

I guess my whole life of dirt biking revolves around, light is right, I had the first 2000 rfs 520 and thought it was great till I got back on a 300, I am 57 now and have had some 2 strokes with huge hours also! You just cant go wrong with light!
 
What's nice about the 2 stroke is I can rebuild it down in a sh$t hole where my 450 ill be taking the motor out and droping it off at the Honda dealer with a big 3,000$ check that won't clear..lol.
 
With good maint... the 4 stroke bikes have flat out proven to be rock solid reliable...

If you dont change your oil every ride or two and you dont take care of your engine... then... well, there you are in the hole.

how does the 300 pull a 136?
 
I wouldn't be scared of the 4-strokes at all. I have friends that wont touch them because they think you have to mess with the valves every 40 hrs or whatever..... but I don't worry about that. I've checked mine a few times but nothing big-- just listen to your engine and act accordingly. The only time mine needed adjusted I could tell because the bike started being harder to start. I do like 2-strokes- but got tired of mixing fuel....
 
working on 4 strokes. lol/ change oil, clean filter, ride hard.

I probably have 300+ hrs on my 2003 yz450 and the valves are still in spec. my 3rd year of owning it and she just keeps going....and going....and going...

my 2010 yz450f is light I can flick it around just as easy as my buddies cr250. 2 strokes may indeed have a place in the market and big bores are wicked cool for snow bikes but 2 stroke are taking a back seat these days man. :present:

I guess KTM didn't get the memo. Different strokes for different folks but 2smokes are far from dead.
 
I agree, 2 strokes are so much better in the single track. The KTM 200/250/300 are far from dead. Look at some of the Enduros going on and you can see the 2 strokes are not going anywhere. They are lighter, have no engine braking, and don't push in the corners throwing you off line. A 300 is on rails compared to a 450 in the tight technical stuff. Both are great bikes but once you throw a leg over a 300 you will be wondering why u didn't try one sooner !

I know some companies are investing in 2 stroke technology because in the future it will come down to cost and EPA requirements. In the next few years your dirtbike/atv for example will not be allowed spill a drop of fuel or oil onto the ground making fuel injection systems even more expensive. Some of the carbed 2 stroke tech is cleaner and more EPA friendly than these EFI 4 stroke engines. Whoever can do it cheaper and cleaner will win LOL. Food for thought
 
Both 2 and 4 Stokes are great bikes I ride both, but after throwing a leg over the 300 ( on dirt)I haven't even looked at the 450. Now I haven't rode it with the MH yet so I can't comment on that yet.

I here it does pretty good ! I can't see why it wouldn't, it's lighter than a 450 and has as much power as a 450. Maybe a little less torque. Thats where the Millar Racing Twirp ported Monster CR500 comes in LOL
 
I think bike selection all comes down to the rider.

I am 235 and pack 20lbs of gear. The bike for me is a 570 Husaberg with a LT.

I have a riding buddy that is weighs in at 180 and has no gear, riding a 505 KTM with a ST. We do the same climbs at the same speed in the spring time conditions. We did not do any side by side in the deep powder. We are both very tight tecinal tree riders and there is no disadvantage to the LT, even in the hard spring snow. When I am on my game we are nose to tail in the tightest of trees.

I have another riding buddy on a 2013 KTM 500 with a LT. This is an awsome set up! Starts on the button every time with very little persuasion, runs smoothe, has almost as much power as my 570 Berg, and rails just as hard in all conditions. The only thing that is more difficult is making a custom air filter adapter for the conical air filter. Still not a big deal.

Riding 2012 KX450 2014 ST kit. Much lighter and flickable on the hard spring snow. It was set up with less ski pressure and felt much better on the hard snow. Railed through the trees awsome but I could push the front end unlike on my heavy ski pressure Berg. If I were 50lbs lighter I might have this setup.

I love my big bore, long stroke motors with the LT for the light Colorado snow.

What He said!!!!!X2 that being said I'm still going to build a 3Hunny
 
Ya weight is nothing really. Until your on a crazy technical hill and you have to pick that heavy thumper up over and over LOL. Although that FI 500 would be sweet to start now.

My old 08 KTM 450 was a bear to start after it got hot. I even had the YTZ7S battery in it and once that was depleted you might as well have thrown it off a cliff LOL. I had every cooling device made on it LOL. It just didn't like slow technical climbs. Those 4 stroke bikes are awesome for wide open stuff. I never liked mine for single track though. I was fighting it all the time and after 80km of single i was spent. 300 i could just ride and ride.

I'd like to try a turbo 4 stroke 500, although i can't see the clutching letting you use all the power like on a CVT sled etc. That and initial cost would be as much a turbo Nytro, Apex etc. The latter is prob a little more exciting on a pull imo.
 
sno dust

When the dust settles I think the 2 stroke vs 4 stroke question is not weight and cost, but which power delivery works best in marginal snow conditons, read: as in powder. So far on the sleds the 4 stroke power delivery means big trench, that 4 stroke power delivery that gives good dirt traction on a 4 stroke, is just what fragile newly compacted snow can't handle, the 4 stroke power delivery ruins the set snow your track has just compressed.

I've ridden some high dollar light weight 4 stroke sleds........sorry......grade c at best. Lots of power for sure but not good for getting up on top of the snow. 4 stroke bikes same deal, ride one in the swamp, or real loose sand or knee deep mud........not good. oh and my three 4 stroke bikes are noisy with quiet mufflers.
