NKW570's FE570 Ride Report

Well, I finally managed to get out on my 570 today and did a 100 mile trail ride.

Due to flooding, the conditions were very wet, muddy and slippery, so perfect to try out the Berg.
I race 4 hour enduros at clubman level and ride fast pace trail.
The terrain was chalk gulley inclines with raised roots, boggy mud, woods, grass and shallow to deep ruts.
I like the big bore racing four strokes and having ridden a 400exc, a 450 exc and a 525, found i was fastest and got most enjoyment from the 525 in all but the tightest wood enduros where a 125 2st would be preferable.
For 2008, i raced a 530 exc-r so thats what i will compare the 09 570 to.
I cannot comment on the fe450 as i have never ridden one.

The stock clutch on the 570 is extremely good, but i opted to fit a rekluse pro and a LHRB. The pro on the berg is the sweetest gear change ever and i can find neutral!Apart from the rekluse and a 14t front sprocket the bike is straight out of the crate and has standard way soft springs, no clicker adjusts, no damper unit, no map switch.
Obviously i will be making some mods and adjust/fine tune and probably fit my scotts but its debateable whether this bike needs much doing to it at all. It is without doubt the best suspended bike from the crate i have ever ridden.
I think this bike will favour softer sags than even the golden rule. I dont know what husaberg have done with the wp susp but it beats the hell out of the ktm.
My 530 was snaking and the front end flapping so i had to work on the suspension big time to get it to work well for me.
When i started the day iwas thinking 'have i overcooked it choosing the 570 ? will it be just too much too handle ?
The answer is no, the 100/72 bore &stroke works great on this bike, its smooth with the FI, ultra responsive and the whole package is very forgiving for a motor which is nearly 60cc more than the 530.
The 570 felt a bit skittish at first maybe the engine position but you get used to it very quickly and it tracks straight and true. The front end is lighter but doesnt climb out of ruts and it doesny wash out like my 530, i came off twice last time on the same route on the 530 as it had a tendency for the front to suddenly tuck in and send me over the bars even with a damper, none of that with the berg.
Is there less inertia/rotational mass with the berg ? Yes, probably even less or close to a ktm 450.
Does the 570 pack more of a punch than my 530 exc-r ? Yes it does but its very much like the 530 as its not snappy or violent.
Like any big bore 4st, its easier to ride when you are going fast and where the berg excels is changing direction or lines quickly, it does this far better than the 530 without putting it down because the 530 was pretty good at weaving in and out of trees.
The 530 is a good bike but the berg is just plain better and that makes me feel abit better after having spent far too much for a dirtbike. (but, i couldnt wait ).

Thats about it really, it does everything well for the mo. Next report would be racing back to back fe450 & fe 570 and alongside ktms 250/450/530.
Any bad points? Id be nitpicking really, but the rear end seems like a large mudcatcher, watch the pointy bits in the rear fender if they catch your leggings when you mount /dismount. Wheelies are a bit wierd, when you get to 45' its like the cyliner head is working against you to go any higher, its saying dont show off or i'll have you off!
Oh one last thing for the kickstart fanatics, the berg is heaven to start with the FI, freezing cold, boiling hot, choke in, choke out, up a tree, in a hedge just one push of the button and your away.


Cheers Nick

The previous ride report was a couple of weeks ago and ive done a few mods for the next rideat the weekend.
As pic shows ,i have fitted a sub mount scotts damper and raised bars.
I have fitted a heavier 84 spring to rear, 14/52 gearing with longer chain so moved the wheel back a bit and a mapping switch.

FE570 Ride Report No. 2

NOTE: THIS IS NICK'S SECOND 2009 FE570 RIDE REPORT THAT I MOVED INTO HIS FIRST RIDE REPORT. DALE E O.

This is the most exciting time for me, as the 570 ride reports start appearing and after a few hundred miles you start to appreciate how good a bike this is.
I have covered nearly 300 miles now and my second ride was a 100 mile trail in a new area, so it was a totally blind route, mainly mud ruts, grass, some deep water sections and a few boggy gnarly rooted bits.
See my previous post, but for this ride the changes in a nutshell were:- 14/52 gearing, wheel further back, sags checked and heavier spring fitted 72 to 84/250, risers and sub mount scotts damper fitted and the mapping switched onto soft.
It just gets better really, i dont miss my 530 exc-r at all, the 570 is better in every department, it weaves thro trees and changes direction more easily than my 400exc !
I wont go into detail on the ride as you have my last report and valley forces except to say it did everything very well and no offs. Full race report wont be until March.
So, a few new things to pick up on:
In chillis report on fe450 ( excellent write up , thanks) he said about the light rear/heavy front scenario. I did not find this at all with the 570, the relationship front and rear was really good, if anything , the front was quite light but planted and tractable so it didnt climb out of ruts or tuck in at all which seemed perfect. It was so good i had the damper virtually turned off, just ready for high speed hits/deflection. The rear would occassionally break away , but it was predictable and i have not touched any clickers yet.
The EFI was flawless as usual and the bike didnt miss a beat going through ice slabbed wwater up to 30" deep in places.
Bit disappointed with the FI for fuel consumption, the bike cut out a couple of times on a steep downhill section and warned me that the fuel was close to out. I reached a gas station and filled up with 7.8 litres. I had coverd 69 miles. I dont know why, but i thought FI would be better than a carb but its worse by 10-15 miles over 8 litres. My guide for the fe570 would be , trail 70 miles max per tank. Racing 45-50 miles max per tank.

There was a snotty bit with deep ruts and a large angled polished root to get over. I got the front over but the rear spun off and dropped down into the rut next to it. The guy in front on a 525 lifted the rear of his bike back into the upper rut when the same thing happened but no way could i lift the berg out using those grab handles or anything else, thats when you realise that the back end of the berg is heavy at a standstill, it took two of ust to lift the back end in position. Those grabhandles just have no leverage at that height to lift straight up, they may work if the bike is on its side to pull it back up towards you though. Its not a big deal but it could catch you out in the middle of a race if you had no help.

The final thing is the mapping. I had this on soft and it worked fine but idid notice its like it has a rev limiter coming in early on 1st and 2nd gears which sometimes stops you lifting the front wheel instantly when you want. This is not the case when you get into 3rd and the wheelie type power comes in again. So , on the basis that i had no problem on the last ride with traction, i will change the setting back to standard for the next ride and experiment with it in aggressive mode as well.
Dale, i look forward to your ride report on your 570, I love this bike.

Cheers, Nick

Hi Peter,
I know nothing about EFI mapping, but i think you could possibly do some fine tuning with the rpm/torque powerbands and even custom map once the diagnostic user tool is available for 09s.
I can only give you my reaction to the three map settings i have on my switch at the moment.
On soft it was like a restriction of power on the bottom end, i.e gears 1 & 2 , still perfectly useable though you could spin the back wheel to clear mud and blip the throttle over small obstacles, but if you gave it a handful, you would not flip the bike over because the rev limiter would come in early to stop this. Once into 3rd gear, the resriction is lifted and the bike would wheelie right over if you let it, so it becomes the same as standard right through to6th.
I am not convinced that soft gives you any more traction down low than using the throttle properly on standard, even in the stickiest conditions. Infact it could even work against you when you want to give it a quick burst to clear alog or spin back over a root and for this reason i have changed back to standard.

Standard has ample power, torque and rpms right through the whole range on the 570 for mud, tight woods and racing. Also , iwould think that standaed would be set from the factory as the best mapping for all round usability.

Agressive really does make a difference. This setting comes in strongest 3rd thro to 6th and boy, does it kick in some power! I am not kidding, i have 14/52 and if you click into 4th at over 40mph and whack the throttle open, the front wheel comes upt 12 o'clock and will carry on thro 60mph before clicking up.
This maybe could be used for open field racing, desert, sand and supermoto.

Cheers,
Nick

Hi Dale,
Could you delete the big pic of my bike please? Its making the posts on this thread about 2 miles long.
I know , it was probably me
I'm sure you will put me right :lol:

Cheers,
Nick

Hi Dale, Thanks.

Are we getting any feedback on your 570 ?

:clock: The secrecy is killing me!
