Babies get a new pair of shoes
« on: December 02, 2020, 11:51:04 PM »
It's tyre time again....

For the R860 off come the detestable Shinko rim protectors and on go Pirelli Sport Demons.

For the JPS it was a forced choice, the Continental, Metzler, Michelin and Dunlop importers all said "maybe next year", but the Avon importer said that they could scare up a 19" front (which was the problem for the others), so Avon it is.

The 860 was the easiest as it is 18" front and rear, although with the K100 front wheel it takes a 100/100 front and a 110/100 rear. I am currently having a bit of a love affair with Pirelli - both the GSA and the KLE wear Scorpion Trail IIs and I love them to bits. So it was a bit of a blow not to be able to put Pirelli tyres on the JPS - will never happen as they don't make a 19" tyre. It did idly cross my mind to paint the ex-R65 18" front gold and slip it on, after all who would know. Then I remembered an 18" experiment on an RS in the 70s and my memory says it didn't go well, however at the time the RS was suffering wobbles which eventually turned out to be a worn top plate, so maybe the problems were not down to an 18" wheel.

The Avons are a leap of faith based on what others have told me. I last fitted Avons in the 70s and I did not like them at all. At the time I was nearly 50 years younger than I am now and went pretty hard, the problem wasd that the Avons hung on almost as well as the Dunlop K81 and K181s I was running at the time, but unlike the Dunlops gave very little warning that they were about to let go. I "lowsided" my nasty little 350cc racing bike twice and thereafter swore off Avon tyres until now.

Obligatory photo of progress below.

Geeze, I have a hard enough time to get motivated enough to change just ONE tire!

In fairness I have been putting it off for a while.
I actually bought the Pirellis before I got sick last year, so they have been waiting 18 months. And everytime I rode the 860 since about April I have whinged about how bad the Shinko are.

So reasonable procrastination period then.

The JPS was more urgent, the old tyres were worn out and 10 years old.

I have run thru 10  (3FRT and 7RR) AM26's on the R65 and I currently have  a set of Avon's on the R1150R
I have never had an issue with any of them
But I am certainly not pushing that hard on the R65 to really tell if they have any bad habits 
We ran pretty hard in the corners (at least for me) the last time  I went to Arkansas on the R1150R and they seemed to hold good   
FYI my Roadster is set up closer to a GS so I am sure other people push way harder than I do 
The R65 is a breeze to change tires on with out inner tubes  ;D

All done.
Too bloody hot to go for a ride so that can wait till tomorrow.

The Avon 3.50/19s are the widest 3.50" tyres I have ever seen, I had to let it down to fit between the ends of the mudguard bracket bolts.

Planning a 200km run tomorrow to shake down the JPS, so I guess I'll know if I like them when that is done.

A mate fell off his bike on a roundabout when it was damp. It was due to the release compound on the new tire
I am told you need to abraide the tyres to remove it.

I noticed that on a set of new car tyres a few years ago. Swatting a new set of Michelin Cross Climates on recently and there was no issue.

A big diesel spill on the A1 last night had me slithering in the car, glad I wasn't on the bike. Like black ice, with that squirrely feeling. My old Saab 9-5 is fantastic on slippery surfaces, she gives your bum a shake and says "be careful". The R65 does something similar with a little shake of her head. Not wham, bam, thank you mam on your asp like some bikes and tyres I've had in the past. Avon Roadrunners being particularly nasty.
