450 vs 570

pne · Sep 16, 2013

Hi guys, I'm about to buy my first 70 deg berg. I'm having a bit of trouble here. I want to turn this bike into a dualsport. Not going to be riding a lot of pavement but sometimes I get the itch to ride to the coffee shop and connecting trails would be nice without having to look over my shoulder all the time.

The 450 I tried rode great, really tractable power I was clutching up wheelies right away. It felt like it had enough for me in the dirt, maybe in the street that would be different. It seemed to handle low speed cornering OK, not spectacular like my 2T but not bad. I only got to ride it for a few minutes though.

The 570 was a beast. Yea it had lots more power but I couldn't seem to put it down at all. Each time I grabbed the throttle it seemed to always want to break the back end loose. Then letting off the gas the bike would lurch hard from all the engine braking. I'm not sure if the owner just had it geared really low or what? Do they all ride like this? Seemed like it just wanted to spit me off. I really wanted to like this bike, can the engine braking be turned down with any of the maps?

Not sure why, but the 570 also felt really heavy compared to the 450. I really had to muscle it around in low speed stuff. I've ridden 450's and the old 550 berg, none of them ever felt this strange.

From my very limited experience, that 570 is probably set up just a little strange. I've ridden oldschool 450, 550, and 650 - and a sloper 570. The 570 definitely felt lighter-turning than the other ones - while the previous gen is "stable to a fault" as someone said on here. I really like both schools of steering feel actually.

The 570 I tried did not feel grabby or lurch-y at all. One of the easiest bikes to just jump on and ride I've used - in power delivery as well as steering. IIRC it was geared a little lower than stock (larger rear sprocket). I think the sprocket wouldn't have made that much difference, although some - the engine character was quite smooth.

Might need an ECU adjustment? (there's some kind of process for it afaik? let the bike idle for X minutes or something?) A while back, my DR-Z's exhaust packing had once been gone for a while and so the carb wasn't jetted correctly for the flow (turbulence in the pipe muffler afaik) - it was really lurchy and the description would have been similar to what you were encountering.

I'd bet that 570 is fine, just needs some normal adjustment.

What gearing do you have? Try riding up a gear from whatever you were in. I recently purchased a 570 and I'm coming off a KTM 300 so I had to get used to engine braking, but it's certainly not lurchy as you described. I also don't find it turning slower than my 300. I'd check your overall setup...sag, fork settings (including location in triple tree's), tire pressures, etc. I rode in some very tight single track with a group of much smaller machines and had no issue keeping pace. These bikes handle beautifully!!

As for power, get the map switch. It won't change engine braking, but it will tame the delivery of power.

+1 on the mapping switch for taming the beast. you can also add the G2 throttle tamer. cant do much about all the engine braking although if you gear the bike higher it will be reduced. consider a cush drive hub if doing a reasonable amount of bitumen.

The guy had it geared 12 52. No sure what it is stock?

HanesAnizer · Sep 17, 2013

12/52 is very short. Stock on a 2011 is 14/42, not sure about other years. I'm running 13/42 and think I will eventually try 13/45.

I think that would explain the jerkiness and excessive engine braking.

^that explains it. I will have to give this bike another shot with normal gearing.

12/52 gearing on a 570!!! That is ridiculously short. No wonder the throttle is a little 'twitchy'.

Good advice.

A smooth hand on the throttle i.e. not ham-fisted, would certainly help also.

thanks, the next one I'm looking at has the map switch and hopefully not geared for rock crawling. I have decent throttle control but it took 90% of my effort working the clutch and the throttle to be smooth on that bike which was an immediate turn off. There is a thing as being geared too low for sure, and it makes the box seem super close ratio as well.

My 09 570 came with 13-52... I first tried 15-52 and found it too steep in the tight stuff, I now run 14-52 which I find a good compromise.

well I bought the 570, took it for a trail ride the other day to try everything out. The low end torque is amazing. Feels completely different than my 2T more like riding a train in the single track. Just point and shoot. Feels like just a wee bit too much bike for me at the moment, but I'm sure I'll grow into it. Whereas the 450 I felt I could have hopped on and rode it hard, this one commands a bit more "respect"

Picking the bike off the ground was not as bad as I thought. Picking up the rear when stuck was a real pain though.

HanesAnizer · Sep 25, 2013

Congratulations!! Awesome machines....the trick on picking the bike up when stuck is to not get stuck

I've had mine stuck in some serious mud and damn near wore my butt out trying to yank it out. That's the only time the weight has bothered me.

Good luck and with the new ride!
