Front end weaving after new tyres
« on: September 23, 2021, 01:21:19 pm »
Hi folk, I need some help please. I recently got a 2018 690 R with very low kms, under 3k. It runs great however after installing some D606's front and rear I get a weave at just over 100km/h on tar, to the point of not being comfortable in going any faster. This is not normal as I've had these tyres before on my BMW XC with no hassles.

I also had rim locks installed and my best guess at this point is that it's a wheel balancing issue?

Your thoughts?

How many KMs have you done on the new tyres? They often need some time to "bed in".
Are they uni-directional?... maybe fitted on the wrong way round.
Check the pressures. Some tyres are very finnicky to pressure settings.
Balancing could be an issue as well.

Did you do any mileage before the tyres?

Might be bedding in as mentioned, but could also be a weird suspension setting, too little rear preload maybe?

Nope no real mileage yet, about 10km or so.

Pressure is good, all else seems fine.

I will report back over the next few rides. Feels like I'm moving into tank slapping territory beyond 110km/h

Thanks guys

I also had 606's on my 'Alp... they scared my constipation right out of me  :o

Took them off after about 80km and fitted Kenda K270's. Never looked back

Had the same phenomenon on my X challenge. They do improve a bit after a bit of mileage but never quite come right. May be ok on a bike with an adjustable steering damper, it might be incorrect practice, but my head bearings are 'pre-loaded' a bit and it helps.

They're good tyres for grip on tar and dirt, and they're cheap. But they don't last very long and they 'weave'. I'll live with them until they're well and truly moertoe because I can't afford not to.

But I won't get any more.

My 690 had Dunlop D606 on the front and rear when I bought it and the weaving fast side of 100 km/h was very unnerving, I really didn’t enjoy the bike.

I changed to Pirelli MT21, the 2014 model I have came out with these as standard fitment, and have not looked back and gelled with the bike ever since.

Thanks guys. Sounds like par for the course. Will live with it for a bit. I mostly do dirt here anyway with odd bit of tar.
