BMW Technical Q&A, Primarily R65 / Re: Upgrade kit run in
« Last post by dogshome on September 22, 2022, 04:48:55 PM »
Doesn't sound ideal but not bad. You will need to change oil and check tappets during that period. Mine took about that long to fully bed in But I experienced no hot running or hesitation. It needed a few hours at those revs and a bit more to develop final power.

Technically running long periods at constant rpm is bad and varying loads and heat cycles is better. Where are you going? If lugging up the Alps then maybe have a rethink! If the speed and load is down to you on the flat, then that is better. You are then in control.

Staying in town won't bed it in and getting on the open road at moderate, varying loads and revs is best. The low standard gearing makes that and avoiding lugging as an 860 easy.

I'd doubt you can go too far wrong here, but a long thrash up a mountain on a hot day at a constant heavy load would be the way to make it wrong.

BMW Technical Q&A, Primarily R65 / Upgrade kit run in

Hi everyone,
Long time no see! Hope everyone's doing OK?... I've got a decent ride coming up and could fit the 860 upgrade kit for it if I got my A into G in the next week. It'll be a ride of 2000km. Just wondering what people's opinions are of running in the upgrade kit on a trip that long if I got the first 200km done around town varying the revs? Keeping in mind once on the trip that it will be at open road speed, so will be long stretches at 4500-5000rpm.

Metzeler site says DO NOT go over 45PSI. Your just talking to lawyers at Metzler  Think about it, you ride around on the road at that pressure hit'n pot hole and such, they wouldn't suggest you do that at the ragged edge of blowing off the rim!


 My mate (who was a lorry tyre fitter) says +50% on 42 which is 60-65 ish. I think that is reasonable and anything higher a cage or be standing on the other side of the wall.


The old front tyre is laughing at me I swear  >:( Do you feel lucky, punk? Do ya?  :uhoh2:

It's on. 60PSI, a gollop of blue KY jelly and a ride up a bumpy road  :2vrolijk_08:

Metzeler site says DO NOT go over 45PSI. My mate (who was a lorry tyre fitter) says +50% on 42 which is 60-65 ish. He also said soapy water won't do it and he is right.

I've had to use 60 psi and that with a relatively easy to mount tyre.

Someone mentioned safety and insurance on the thread above?  ;D

75-80 PSI  :uhoh2:



Any feedback from others on this? (I'm still looking for Kahoonas)  :laugh:

" Putting 45 PSI didn't do it and I won't try higher."
I have gone to 75-80 on some tires before the bead would POP.

I can confirm these are a very tight fit on the bead. The bead had not budged despit being pushed 500M and then powered to get on the ramp of the truck, dead flat.

The new one is on and is a much better fit than the 120 in the swing arm. However, the last part of the bead won't rise up. Its been bounced, deflated, lubed etc. Putting 45 PSI didn't do it and I won't try higher. I've put it on the bike to see if a bit of bouncing and rolling will do it (hasn't yet) and have ordered some proper bead lube. Plan is to deflate, hose out any remaining dish soap, brush some stuff in and re-inflate.

The front one is looking like it will also be a SOAB. I have two 18" levers, plus three in the toolkit. All were needed to get both beads on. Combined with some plastic cut from a 5L can and some care, no rims were butchered today. I've learned things again and hopefully 'buy proper lube' is going to be one of them. The other is 'don't think of changing a modern tyre at the side of the road'. I don't remember having this much aggro back in the 80's, Trail tyres almost threw themselves off once deflated and road ones were just a bit tougher than pushbikes.

While the concern of voiding the insurance is legitimate, unless wheel/tyre combination was clearly the cause of the accident, it would take an awfully clued up insurance investigator to spot the issue otherwise.
After all Snowflakes are something of an exception, it's uncommon for alloy wheels to be designed for only tube type tyres.

I haven't yet tried to run tubeless simply because I've always bought tube type tyres but my view of the safety aspect is influenced by the difficulty of breaking the bead. Tyres don't come off a snowflake that easily do they even when fully deflated.  Due to their stiffness I've no doubt that tubless tyres are even more difficult to break the bead. That would make me tend to worry less about snowflakes lacking the correct profile designed to retain the tyre in the event of deflation.
