It’s been about 10 or 15 years since I’ve even touched an RD in terms of working on, tuning or setting one up. That said I now have 2 air cooled 125’s to sort out and an N1 (31k) that came in boxes. One thing I have noticed is the pool of parts is significantly smaller and the stuff that is out there is pretty rough.
Anyhow, are BT 45’s still the way to go with a YPVS? it’s got new BT45R’s on it but they are dated 2008 so a bit sketchy….

Avon are good, but im not sure about BT45's, as I think they are now superseded by the BT46. I assume that this is as good, if not better than the 45. Dont rely on 14 yr old rubber, this applies to tyres or condoms

Dont rely on 14 yr old rubber, this applies to tyres or condoms Old tyres are sketchy but a recent experience makes me wonder. I picked up an Aprilia RSV1000 not too long ago to keep the RSV-R and Colin Edwards replica company. It’s on Dunlops and as far as grip and feel it’s beyond many similar bikes. until I checked the boots - 2003! Anyhow, Bridgestone we’re always without doubt the optimal tyre choice for an RD but a decade has passed hence asking… Avons, ummm… they have always been the budget choice so not too sure on that

Been running BT46`s on the 4L0 350 on the road for the past year , feel good to me, a very ex racer who rides "Briskly" on the road now.
Not got much to compare to though, the other road bike is a TL1000R, running on Avon Venom Hypersports or something , which at a couple of years old where not gripping very well at a very wet Donington Park track day last year, ok in the dry at Mallory .

I think that bikers in general are very aware of their tyres in comparison to other road users. The biggest killer for tyres is UV light as well as sitting in the same spot, causing flat spots. There was an accident some years back when a coach tyre that was 19 years old blew out and I think there was one fatality, so an age rejection criteria would be good. Where the standard would be set I'm unsure, as the tyre companies would say 2-3 years. The touring caravan industry say 5 years which I dont think is unreasonable. Most bikers end up sticking with what they know. A bit like marriage

Bike manufacturers say 10 years
Up to 5 years in storage before fitting is apparently ok
Found this out during an argument when Demon tweaks sent out 4 year old tyres 🙄
If it's been stored in a dark cool place and the rubber is nice and soft I'd give them a go lol
My ypvs has tyres dated 2012 on them but they are fried and blue 😬

FWIW
I have used BT45's and Avon Road rider 2's on my stock 4LO (sorry not a 31k) and the Avons are streets ahead (no pun intended!) in every department, in my opinion.

An old used rubber is OK as long as it’s sticky. Be careful of small cracks though as you’ll be in trouble if it bursts open while your going full chat 🤣

That’s a little off, can you imagine getting 4 year old condoms and the seller saying they were stored in a cool and dark place - he could mean Wesley Snipes for all we know!!

I highly recommend Avon Roadrunners if you can find some old stock somewhere. I'll add a smiley face just in case there is any doubt I remember getting wheelspin in the wet with an Avon Roadrunner on the back. I was doing about 80 with approximately 5° of lean angle from the vertical at the time. Race and road tyres where a thousand miles apart at that time. There's nothing in it now. While I'm rabbiting on I remember a road in the town that had red tarmac on it. You could do maybe 30/40 in third/fourth and just whack the throttle open in a straight line and get massive wheelspin in the wet. It was fun and felt quite safe if you were bolt upright but the low level of grip was legendary.

It’s a funny thing about dates on things like this. I’ve had Arai helmets for years. One time I had a helmet that was in perfect condition, but was 8 years old instead of the recommended max of 4. When I bought a new one there was no date on it. I was told it was to avoid punters haggling on a helmet with some of the recommended 4 years taken up by storage etc. it was left down today the owner.

Found out riding back from work yesterday and practising hard stops that BT46 front makes a useful chirping sound as it locks .
( I practice locking the front wheels of the road and dirt bikes as part of my regular training drills )
Despite everyone saying stock 350LC brakes are crap, never found them lacking power if they are in good condition with good pads, but they do need a good squeeze compared to modern stuff. Single disk 250 would fade even with race pads at Mallory, helped with corner speed at the hairpin but scary !
Currently running a 250LC Master cylinder for more feel and less force , braded hoses, pads unknown, one of the few things that were not completely worn out when I got the bike.
