Those Avon’s seem worth a try. Although now that I went to Pirelli Angel GTs for Tour/Trip it will be a while before I need tyres. Not like when I ran S20 & S21 as it was only a few months between the tyres changes, lol

In January 2018 the Michelin Road Pilot 5 comes out. Lols like an awesome tyre claiming the same grips as a new PR4 after 3000 miles.

Going by the picture above, it looks like Michelin have taken the criticism of the PR4 on board - why have all that siping to the edge when you're not going to be cranked over that far in the wet? All that siping just destroys dry "sport" performance, overheating the tyre when you're having fun. Looks like Michelin have done the right thing, there's nothing wrong with the PR4's compound, it's the excessive siping that most sportier riders have been complaining about.

Although they will still be a heavy carcass tyre which is added unsprung weight for the suspension to control and cope with. The PR4 bias is tad too much to wet weather which is ideal for commuting all weather tours but not so sporty machinery which does be out in the wet unless caught out and then it’s TC3 and easy does it to home or ferry port. Liked PR4 on MT-09 but always thought -10 too much a bike and a tad vague front end feel on turn in. PR5 May be better. Pirelli Angel GT sportier side swung me over to them from liked S21. Sporty S21 life a bit too short for big Trip Summer Holiday Tours.

Yes the Angel GTs are very good - but if you like your tyres light then give Avons a go - they are usually the lightest tyres in their class. Very soft carcass which flexes when cranked over giving you an increasing footprint the harder you push. Actually it's a bit more technical than that - they have a variable density belt winding which means the carcass is stiff in a straight line but flexes as you corner to fatten the contact patch. I've been riding on these salty damp roads - very slippy - the Avon 3D Ultras have been hanging on like a limpet despite being a mileage biased tyre - then for comparison I took the Triumph Thunderbird out and had two hairy moments (spinning the back wheel up at 70mph+) something I don't have to worry about with the MT-10 with its TC. BTW my Thunderbird has over 170 bhp at the back wheel before you ask how the hell can I spin the back wheel up on a cruiser! I think the Michelin Commander II is just a bit too hard for this kind of hooliganism - Avon Spirit STs going on next. All that said - if you find no fault with the Angel GTs then stick with 'em. You might like the company's sister tyre even more - the Metzeler Roadtec 01, it's like an Angel GT but slightly better in every area - it's the newer tyre so I'm not surprised, I wouldn't bet against a refreshed Angel GT coming along which will be a slightly reworked Roadtec 01.

I've watched that before - looked like a cool trip.

I had the Bridgdestone T31s fitted in the summer. The carcass was a bit heavy, I could feel the difference in flicking the bike side to side from the S21s I had before. Great wet grip, never had a brown pants moment on them (yet) although I didn't push them quite as hard as I did the S21s . They warm up quite fast, and still look like new after 3000 km, when the S21s were almost finished. Can't fault them. I'll probably take them to the Alps and see how they do there, but given that the pavement is much more grippy there, I don't think lean angles will be an issue.

I replaced the OEM S20's with S21's when I put on the new wheels and they are a big step up from the 20's. I have had good luck with them to this point.
The new Michelin Road Pilot 5 looks interesting.

I think that I am right in saying I read that the previous T30 EVO front tyre wore out at roughly the same time as the T30 rear. In other words you replace as as set and not the normal two rear tyres to one front tyre. Just saying wondering is T31 the same.

I am going to go for the Michelin road 5,i had the pr3's on my zzr 1400 loads more bhp than the mt10 and no traction control and they were great,so the 5's should be more than capable with 40bhp less.

Should be really good road tyres - unless you're planning to go belting round tracks then there might be better alternatives.

I just did a track day with the S21 front and T31EVO rear. It went better than expected for the most part, full lean, full throttle, knee down, lapped even some of the instructors, but I had a big moment on an uphill gearchange when I dumped the clutch a bit too fast and the rear wheel stepped out. TC saved my ass, literally. I believe the S21R wouldn't have slipped. It was good to have enough rubber left for the rest of the season though.

Sounds like you're a lot quicker than me - are you saying you can genuinely go full throttle when cranked right over and just let the TC do the hard work? I just haven't had the bottle to try this on the track - I still ride like I haven't got TC and feed the throttle in gently.

Track days do feature a bit in the S21 tyre Design and I’d say not so T31. However, I’m of the thinking everything can be raced and that everything can also be toured; if you get my drift. I’d guess the TC (TC1 allows some drift) may have helped yep and or just natural re-regrip. I do feel Angel GT grip less than sports S21 but on the road are brilliant and last well over more than twice distance. A Better rear shock helps would help ya to. 👍
