Pilot Road 4s on a sportsbike?
Discussion
Your Blade will melt the PR4's in minutes causing the bike to squirm then high side you off in spectacular fashion. Anything more than 40mph and the blocks may be ripped off by the shear power!
You should be fine. They'll be a bit slower on the turn in than a more aggressive tyre, but more than capable. If you go out on the track then you may have problems in warm weather at anything more than novice pace. For day to day road use you wil be good and unless you want more feel and are tearing up the edges then they are a good buy.
My brother took his daily ride out to Brands this year on PR4's. They overheated pretty quickly but it was July and he's a fast-ish rider.

you'd be fine in the bottom end of Fast Group on those tyres and will struggle to outride any modern modern sports or sports touring tyre. Too much flapping about tyres on here. You should be fine.

They are fantastic tyres and will now be putting them on my KTM 1290 SA.PR4s work fine for fast road work on my K1300S, (including some very spirited rides in Spain where temperatures were in the low to mid 30’s C) which is heavier and more powerful than the ‘Blade. Perfect tyres for road work and fine for the track unless you plan on being the fastest on the track.
I did find that the PR4s are far more sensitive to pressures then the PR2s. I used to run my PR2s with a couple of PSI below the “official” 36/42. This gave slightly better grip and feel without any loss of stability. Doing this on the PR4s caused unwelcome movement towards the limit in corners. I contacted Michelin and was advised by the Michelin rep to run them a couple of PSI harder than standard. This solved the movement problem and made them totally stable. The Michelin rep said the PR4s have softer sidewalls than the PR2s or PR3s hence not liking the lower pressure, and hence the PR4GTs, with stiffer sidewalls, for the heavier touring bikes.

What Loon said.My mate and I both got new tyres just before this years euro trip and he went for PR4s on his new Blade and me with Pilot Power 3s on my F4. While obviously not going at a track pace we did a lot of spirited riding and had a few torrential downpours to ride through. He was absolutely fine and also his appear to be wearing better.
Give the guy a little break. Clearly newish to two wheels he asked a serious question about tyres. Obviously woefully miss informed by others, but not a crime asking to make an informed decision on tyres.
As has been said, PR4's will be fine for 99% of riders on the road, but if they're anything like the PR3 on the track they do suffer from thread block movement. But easily manageable if your in novice or inters.

How much and what sort of riding do you plan on doing?
If you are mainly a summer season rider and do upto say 5k a year metzler m7rr or Pirelli corsa may be a better choice.
From places like tyre leader they are pretty good value, normally less than pr4. They won't last as long as the pr4 but they are ok and will feel nicer even if you aren't going to use all the grip.
I seem unlucky with tyres and punctures and my logic is I'm less likely to pick up a puncture before I've worn out a m7rr than a pr4. Thus any savings on the extra pr4 mileage are taken out by either having to replace the tyre early or pay for s quality repair.
If you are riding in cold and wet then pr4 no doubt.

I have PR3s on my 675.
You will be quick in the wet on them if you do trackdays - PR4s are supposed to be even better than PR3s for standing water and the PR3 are superb in the wet.
They might make the bike turn in slower however will feel miles better than a pair of squared off softer tyres! The new PR3s on my 675 felt so much better than the string of quickly squared off dunlops i'd had on it before.
Happy to be using Pilot Roads again - great tyres.
