A test report for V11 tyres

"Subjective" [observation] is used when there is not a predescribed testmethod that would result in measurable repeatable values(objective method). I think something like feedback is difficult to capture in an objective sense.

Absolutely. They did have some measurable metrics that were quantifiable. But even those can be subjective. Such as the lap times. Those are good metrics, however the test pilot will not drive the bike exactly the same way for each lap.

For example, if we assume the testing was done in the order published in the report, he started with the Michelin. We don't know if he did some free practice laps before he started the test. Would it make sense to say that as he accrued laps, he felt more comfortable and could go faster?

All the impressions on corner entering, cornering, corner exiting are based on his own appreciation. But he supposedly uses the same for each tire. While there is no accurate methodology, I would think he followed the same procedure and process for each set of tires.

Although I really am not enamored with the name about which I'd have to roll my eyes if anyone asked about the tire, has anyone checked out the Dunlop Mutant tire?

 

It has some pretty impressive reviews, and seems to be a great all-around(er) tire, especially if your riding includes a lot of wet and poor roads.

Very true.

But if I read the report measuring the temperature increase was part of the objective part. 

Braking with ABS is reproducible.

ASR when coming out the corner also says something, especially with the track logger that they used. Lateral and longitudinal accelerations are usually pretty accurate on the logger.

But still true, these tests have also subjectivity because of the driver preferences/capabilities.

A fairly new offering from Dunlop which popped up on my radar recently as well. No personal experience, but I've read mostly raving reviews from testers. Definitely interesting construction and looks. I'm highly considering trying them next, they could be effective around here as the tarmac on secondary roads is often in bad shape. Albeit not on the V11S but on the Griso. I think in terms of looks it would suit the Griso nicely and even maybe in name, as I think of the Griso as a bit of a - dare I say it - MUTANT.

Ha ha 

Griso as Mutant....!

I get it and don't think I'll look at one the same again now...
