As above - i got some of these based on the reviews and forum posts id read (don't think there have been any ive read on here though) Gotta say: not impressed atall. I initially bought them to replace the supercorsa's on my RSV4. Stuck them on and after a scrub in felt unsteady, and no matter what the conditions always felt the same....i got another bike (z1000 2014) that came with a shagged set of squared off dunlops...the oem tyre on there as it had only done 4k and although ive never had a set of dunlops on there they felt really good in the corners (they literally were on there for the journey home) - anyway, while the opportunity was there i got another set of SC's for the RSV4 and put the M7RR's on the zed and they still feel the same. Its a sunny day to day in Bristol, rode to work on it thinking ill get it right over and see if its just me...nope....pretty well any corner i go into on the exit if i give it some the back comes right out and im no where near the edge of the tyre. So, im gonna run'em til theyre knackered and then try something else...Dunlop this time i think...working my way through the manufacturers but at the moment the supercorsa's rule... i know they've not got the longevity of the other tyres but ill sacrifice a bit but not the jump that i can see between the 2... Not really a moan....you've gotta try stuff out....that's the way it goes...
Hard to agree with anything you've said to be honest, as the M7RR is a terrific tyre by any account. To have 'the back end go out' on the road is questionable! That being said, if you like SCs, you should try DRCs on the road instead. Better mileage, and the tyre carcass profile is similar. Plenty of grip and feel for road and even inters track pace.
Hmm. On my second set of RRs and never had that problem. My SF now has gargantuan bottom end grunt. I frequently get the front wheel lifting and the bars wagging while still cranked over gassing out of bends but I've never (touch wood...) felt the back letting go beyond little shimmies occasionally on shiny surfaces or ridges/lines which you'd expect. I'm more careful obviously when I'm getting round to the edge of the tyre but they always give me the confidence to get on the power early. They're also blinding in the wet where Supercorsas were horrible. What pressures you running? I stick to 35 rear, 33 front. Seems to suit me. Any firmer and I've found them a touch skittish unless properly hot.
Yeah - I know....all things equal they should be a good tyre - I really was expecting a tiny bit less grip than the SC's and obviously better in the wet, the loss in grip from the one set to the other I was happy with as the SC's are I would say dangerous in the wet but after riding on the m7's and the massive difference between the 2 I was happy to take it on the chin for the wet weather grip loss on the SC's (and having said that I don't aim to go out in the wet on the sc's anyway) its really a case of "if I get caught out" I reckon ive got about a quarter of an inch of unused tyre on the side of the m7's, now if id have gone all the way to the edge and got the back skipping out then, yeah, fine, id expect that, but im no where near the edge. I mean, I could say, well its the suspension on the zed (the rear on the 2014 model is known, and is, a hard ride) but the RSV4 is a totally different bike and it pretty well felt the same... Spareparts: I wouldn't say im a good rider by any stretch, so I wouldn't say (well I think) im pushing the tyre that hard...went to Weston bike night last night on the rsv and gave it a lot harder time than the zed....road holding was I would say perfect on the sc's....
Possible explanations include: you fitted a sub-standard set of M7RRs; you haven't got them at the right pressures; you are Casey Stoner. My guess is, it's all three
Definitely not the last one.....tyre pressures....maybe - when they were fitted at the tyrefitters they inflated them and I put them on - didn't check the pressures...maybe I should...as I say there are a million better riders out there than me which makes me think its more the tyre than me...I mean if, I come out of a roundabout (not banked right over but a little bit of lean) and then open the throttle and the rear gives (or starts to give) then somethings up... Not sure what you mean by sub standard RR's - Im guessing theyre all the same? or no?
I always check the pressures after the tyres have been fitted. My local dealer gets them spot-on but I don't always have them done there - but I check regardless. Sub-standard tyres occasionally happen, a manufacturing defect. I had a set of Dunlop 208's once where the rear started to "open up" along fault lines and the replacement I got from the same seller started to do the same. A bad batch, I think! No, in your case, it will be pressures I reckon. Always check them.
I'm with @comfysofa here. I too found the M7RR's unpredictable on my Tuono v4. I stuck them out for a while but ditched them for Rossi 2s which gives me the best compromise between wear and fun.
Interesting. Before Comfy posted, I'd heard nothing but good things about the Metzellers and I've been satisfied with them, so far. Mind you, I haven't track-tested them yet. Thanks for posting your opinion.
So, what do you reckon then for pressures? id love to love this tyre if you get my drift (pardon the pun) - everyone says theyre good and id really like to be good! One thing that ive started to do is, make a point of trying different manufacturers on my day to day bike (ie in this case - the zed) - I was thinking of going for the Michelin PR4's next...I mean, (me included - find your comfort zone - supercorsa's for me at the moment) and stick with it but - I need to sample more as there might be a tyre out there which I like more...
I did have Rosso corsa's on my old hypermotard 1100s and they were good....that's kind of a fallback tyre for me - I know its there and I know its good...
My M7RRs are set at 2.1/2.3 Bar on my 999S (31.5/34.5 PSI) At least, they should be. I must check them before the weekend
People make a right over the top faff about it but tyre pressures are definately hugely important. I'd bet my bottom dollar that the tyre place has put too much pressure in them. I reckon you'll find they have ~35-37 psi in them as from what I hear they are very similar to the Supercorsas and they do the same thing as you describe when they have too much pressure in them. I pretty much run any fast road/track tyre at 32psi hot with perhaps a little more in the rear.
ill check the pressures tonight. Is there that much of a difference 1 bar each way? does it affect the handling that much?
Yes. A single tenth of a Bar creates a big difference. Even if you're not Casey Stoner - which I am not!
I carry a small mechanical tyre pressure checking tool in my tool bag on the bike all the time. They are only a couple of quid and the size of a biro.
2 bar is about 30psi so yes a bar make a big difference One or two psi is noticeable but not a huge deal, anything more I can tell the difference straight away with Supercorsas. It definately makes a difference on the handling.
I have a few of these and never found them particularly accurate. Mine we cheapo jobs mind. I've been using one of these for a couple of years nowhttp://www.halfords.com/motoring-travel/motorcycling/motorcycle-accessories/oxford-tyre-gauge-pro-dial-type-0-60psi don't think that its calibrated mind.
That's what I use in the garage or at tracks these days. You'll never get it under the seat of a Panigale though The cheap little biro ones are not as accurate but they are definately sufficient.
