70 Degree Husaberg Folks??

You might want to check with Timbersled if the tss works with that bike. I think I read about subframe clearance issues.

The TSS will not fit unless you are OK with cutting some of the lower subframe out. We have a berg 570 running with a kit on it and the little tab that hangs off it already barely rubs the subframe on the kits. So the TSS will definately give you issues. That being said, don't hesitate to run the 16 kit without the TSS, seriously impressive suspension feel vs older kits.

The intake works really well aside from insanely deep days. we just ran a dry foam filter and prefilter over it. which worked killer. It would randomly need to be dug out but with the quick disconnect on the seat its so fast and easy to do we never bothered to mess with it more. Just make sure to take it all apart after each ride and clean things out as the way the airbox is sitting as the snow melts it feeds the water into the motor.

As for mods, the map switch didn't seem to affect how it felt in the snow at all. We ran an Akro slip on which greatly helped top end which is key for snowbiking a bike that barely turns over 9k rpm. We did run a dobeck Gen 4 on ours and found the stock fuel mapping was fairly close but we liked it just to clean it up extra and handle the fueling for our nitrous setup we were running on it

Unfortunately the bike looks like yours does. Its a run around rig now that its warm out. But if you look at your subframe where the mud flap screws on, shifter side, there is a little tab of it that hangs down, that barely rubs the kits.

If you were OK with lopping that off it would be no issue to allow it to flex.

Some shots of it in the showroom and on the snow last season.

I have a 2015 ST kit on my FE390 and I'm looking to modify my subframe (like you, i'd look to by a second one and hack it up) to allow for the suspension compression of the TSS.

It doesn't look like it'll require alot of hacking at all really.

Or the alt. is to just mock up a fully custom subframe and skip the husaberg one completely.

I was asking about this in another thread and Brent from timbersled gave me this info, but i've yet to have a chance to call and chat with Corrie:

Call Corrie at Brewster West Motorsports in Calgary. (403-933-2424) then post up what you figure out.
I seem to recall a few years ago he built a few 70 degree Bergs with 2Moto kits; and he changed them over to the KTM style rear subframes to get them to mount up. He could tell you if that was easy, expensive, or worth it.

If you call, please write back with any info

Cheers

Jeff

good to know, thx for calling!

I found a few 70 degree subframes on ebay but they are a little pricey @ 200+ shipping.

I have friends with fabrication skills so next year perhaps i'll look @roping them into helping me mock up something maybe

I'll keep updating this thread with any thoughts/plans we come up with.

Cheers

I am also a loving 70deg berg owner. I have scaled my problem down to 3.

The intake is great in stock form with a prefilter over the stock foam. Every once in a while you will bomb a big soft tree well and injest a wad of snow that makes for a temporary stall, but it is rare. I removed the rubber intake boot on my FX450/660 and did a conical air filter straight on the throttle body. I was very happy with this set up even in the 4' champaign powder down in wolf creek last year.

On my stock 570 I run no fuel controller even with exhaust upgrade. My KMS turbo 570 I run PCV and it tunes well. On the FX450/660 thumper racing bike I use Bazzaz with auto tune. I was very happy this this last year. No failures and percise repiedable tuning on all three bikes I ran it on.

The TSS may or may not fit. I tried very hard to make a 2015 SX fit last season and I had to stop cutting when I got to the stock fuel tank and fuel pump in the way. I have a hacked subframe on the 450/660 and will do a TSS test fit on this bike as soon as I get my hands I one. I will keep you updated.

The stator is large enough to support AME heated grips and Cyclops LED 6 or 3 headlight.

I did have a cam chain tensioner failure at -20deg on day. I install manual cam chain tensioners now.

I also do thermostats on my bikes. I can sell you a ThermoBob. It works the best for this application.

Don't spend a lot of time on weight reduction. These bikes are quite portly and have big tractor power to compensate for it.

Wire a 10ga jumper lead from the battery to the out side of the bike so you can hook up a micro jump box when ever you need it. This way it is ready and you do not have to remove the seat every time. You will thank me. I use Balistic batterys with some success. They crank at super cold and have plenty of power, but they are particular on how they like to be treated. DO NOT RUN THEM DOWN AND THEN TRY TO JUMP IT. You will let the magic smoke out. If the bike does not start in the first two cranks hook up the micro jump box and add a teaspoon of fuel on the air cleaner.

The other must I should sell you is a SeatConcepts recover and new foam package. Your hind end will thank me as well. The stock 2x4 on this bike is probably the worst I have ever been on. I have one seat I transfer between bikes. I will not ride with out it.

Respring and revalve the front forks. As soon as you start riding agressively you will bottom out the front. I have some custom wound front springs I have made from .54 to .60 depending on rider weight. If you want the ultimate you can send me your forks and I cand do a custom valve and spring combo for the best snow ride.

One of my bikes takes a teaspoon of fuel on the air filter every time when it is under 20deg. on a cold start. After that it starts every time within a few revolutions.

A carbon fiber header pipe guard is a must if you like your $500 Klim pants.

Thanks Toby, were you ever able to fit a TSS to a 570 Berg? My buddy has a 570 Beg with a 2015 LT and would like to upgrade to the TSS, I looked at the plastic nubby thing that needs to be cut, but am not sure how much can be cut off safely.

I have a TSS in my hands now and will fit it to the Berg next week. It looks as it will fit with some subframe trimming. I will post pics and all. It may not work with a 70deg aux fuel tank.

YES, you need a thermobob. I am a dealer for them. I can ship you one. Your factory thermostat has a flow through and will not fully seal and do the job you need.


I am also a Factory Connection dealer and can have a custom set of springs made for you. $199

I will have an answer and pictures of TSS on a 70 deg. Berg ASAP.

Toby I appreciate all your info Def stuff I needed to know. Couple questions.

Do I need a thermo Bob for sure? Or can I just get a different tempature thermostat for mine?

Also please keep me posted on the TSS if this does not fit my bike Im going to be pretty upset. I knew the cutting of the subframe but that doesn't bother me. It just better fit in general haha.

I will be ordering a cam chain tensioner. And also I found somewhere I can order .60 springs or so I thought. I'll have to find them again.

I found a guy that's going to sell me a SC seat as well as some pegs.

Sounds like my biggest issues to sort out are the TSS fitting. A thermostat solution and my fork.

Spring rate is a spring rate. No real difference. As long as they are the correct size and length for your forks, use them.

I just got finished with the Denver snow show and pulled the TSS that was built for a YZ450f and tried it on a 70 deg Berg. It of coarse was to short but it did give the first look at the fit. The small tab on the bottom is the subframe that the mud flap attaches to will need to be trimmed completely off all the way until it is even with both flat sides. At this point the rear fender also touches the cross shaft and gear of the kit. The stock fuel tank clears nicely and there is nothing that is holding me back on saying TSS will work on the 70 deg Berg. I have ordered one for mine.
