The Sportec M3 demonstrates Metzeler’s
extensive experience with zero-degrees
steel-belted tyres: The tyre bravely responds to the rider's demands, from comfortable cruising to sharp acceleration. In the last case,
the rear wheel is beaten by the competition, having
problems with grip on the gas in corners and also feeling mushier than the Conti or the BT 16. It is probably
not a bad tyre, with a wide range of use. On the road,
the Metzeler runs wonderfully, but as soon as speeds
become illegal, it is less exact. Respectfully, PS awards
the M3 the distinction „fearless workhorse“. It is a true
companion, taking you wherever you want, and, when
spurred, can increase its pace. What more could you
want?

2CT has two rubber compounds: a hard
and durable compound for the centre
section and a soft on the flanks for grip
and reserves. This is nothing special, as
Bridgestone runs with three and Conti runs with continuously changing rubber. Perhaps it's simply time for
a successor to the Pilot Power: it only has to have
performance equal to the 2CT in everyday situations,
sensational grip when cold and wet, extensive mileage,
precise steering and tracking. However, bigger reserves
when gassing it, would be great. The current 2CT
reaches its limit at a certain speed, limps along at the
rear and doesn’t feel good when leaned over extremely
– 2.5 bar at the rear brought an improvement, but not
enough to catch up with the fastest. The 2CT remains
a top everyday tyre.

Last year’s winner, this year’s problem
child: In cold, new condition the Qualifier
failed to impress, surprising us with one
heavy fall and several unexpected slides.
It has to be run in and warmed up carefully. After a
couple of laps, the rear tyre ran extremely hot. Results
improved when the rear tyre pressure was reduced to
2.1 bar, but even then it felt nervous and jittery at a
quick road pace. Then the big surprise; over a certain
pace, the tyre suddenly performed sharply and became
quick. In this field, the Qualifier behaved the most like
a racing tyre, requiring pressure and a quick pace but
could then compete with the best, as the recorded
times show. It didn't entirely demonstrate the relaxed
composure of its fast competitors. It is a tyre for
aggressive riders.

Wow, already the first meters make you
smile, as the Sport Attack rolls, new and
cold, with surprising, almost boring confidence. And it's getting better: the longer
the ride, the better the tyre. Not the slightest uneasiness can be felt while cornering; even down to extreme lean angles front and rear are working together
fantastically. Steering is easy, without becoming nervous. Wonderfully stable during braking and no regard
for chattering. The power of a 1000cc bike suits the
temperament of the Sport Attack and it is only when
rider gives gas at extreme lean angles that it begins
to move slightly, but this is in a range that will never
happen on the road in everyday use. A great tyre, a
test winner.

Almost the winner. Why? Its only weak
point was that although the new Bridgestone BT 16 performed well from cold
for this type of fast tyre, it just didn’t perform as well as the Sport Attack or the Pilot Power.
After all, cold running or even cool running is part
of everyday driving - so points had to be deducted.
But in return this tyre is a great performer. From the
zero-degrees technology to the three rubber compounds at the front or the five at the rear: The BT 16
excels thanks to its excellent grip with unbeatable
feedback and incredible manners, subjectively but
also recorded. The BT 16 is the fastest tyre here,
doesn’t pose questions but has an answer for everything. Hats off!

For an everyday tyre, the Diablo Rosso
gives supersports performance. „The tyre
needs a firm hand,“ according to the test
report. Truth is, the Rosso needs persuasion to follow the correct line into and out of bends.
If you don't treat it firmly enough, the tyre becomes
imprecise; a light crack of the whip, however, and
everything works. It is surprising what grip reserves
the tyre can muster. It is also surprising that at slower
speeds (i.e. on the road), the front tyre almost falls
into corners, but at faster speeds it feels slightly
unwilling. A problem? No, this is only noticed when
compared to the excellent test selection. The Diablo
Rosso is an incredibly speedy tyre with good qualities
for everyday use.
