Supermotards are
suited to the H rated range of radials offered by a number of the main
brands because the bikes are light in weight, not capable of over
130mph, but require stability and handling under speed and braking. The
Z rated tyres available (i.e. BT016, D207e's
etc...) will never be fully utilized by the motards, mainly because the
tyres are designed for much heavier and more powerful bikes. The H rated
radial tyre offers the compromise. Various brands have a number of versions
all mainly geared towards the 400cc supersport and 250cc classes.
We've
found these work perfectly in the supermotard context.

Dunlop GPR Alpha-10
The
ultimate performance tyre for 125cc-400cc sport bikes and supermotos.
The new compounds on
this tyre have been developed for uncompromising grip and traction
control on the road and track. Reduced tread grooves increase dry grip,
but thanks to the cleaver groove design they also shift more water than
the predecessor so safety in the wet is improved.
Riders of mid-sized
supersport bikes demand a lot from their tyres. Many use their bikes on
race circuits as well as the road and being exceptional at both
disciplines was what made the sportmax GPR 70 so popular with these
hard-to-please riders.As thesuccessor of the hugely popular GPR 70 , the
new Sportmax GPR Alpha-10 had to be good otherwise it was dead in the
water. Well, it's not just good, it's incredible and what's truly
remarkable about it is just how equally at home it is on streets and
race tracks.
If a high
performance tyre is what you're looking for you've found the Holy Grail,
and we're not just talking about the huge grip levels available from the
new tread compouds.

THE TRACK DAY or NON LEGAL OPTION.
Many motard riders are finding there way to (tarmac) track days and
while they are going round the outside of most sports bike riders, the
question is still asked, can I get even more grip?
The answer is the race tyre option. They're non-road legal, they wear
out quick, they can cost more, but the levels of performance are unbelievable
(when managed correctly).
Popular options are Pirelli/Metzler and Michelin slicks/ wets for the
5.00 inch rim bikes (with the adequate chain clearance). The only rear
size available from these manufacturers is 160 section and above (i.e.
160/60-17, 165/55-17 or 16/63-17). If these sizes are run on the 4.25
rims the tyre will be distorted and therefore result in a smaller contact
patch (less rubber on the road).
The 4.25 rim brands are Dunlop and Bridgstone (e.g. 155/620-R17 and
155/60-17. Dunlop only produce a slick and Bridgestone produce a wet
and slick.
Supermoto wets.

A dedicated tyre
for Supermoto street bikes
Specifically developed for punchy,
light and fast-handling Supermoto bikes. Mutant has aggressive front and
rear tread patterns, and compounds for high grip in both wet and dry
conditions.
Supermotos - its all about fun
and image.
For fun you want to ensure your
tyres have light and flickable handling characteristics for those
super-quick changes of direction, but this mustn't come at the expense
of stability. You also need plenty of grip for those massive lean
angles. This grip has to be predictable and progressive on the limit so
that those skilful enough can back it in without fear of thier tyres
suddenly letting go.

BT 090 (Bridgestone).
We've had continued success with this tyre from a motard
perspective. Bikes have ranged from the formidable CR500 to the CRM250.
The tyres seem to provide almost the best grip available in addition to
some degree of longevity. We're yet to have any complaints about
performance except possibly a prelonged warm up time compared to some
other brands and their very strong wax layer when just purchased.
They can be used in any conditions, however, muddy or shingle covered
lanes will pose problems due to the lack of a dispersing tread pattern.
We've had very successful track day reports particulary from KTM LC4's
and Husky 610's.
Depending on the riding, you can expect up to 3000 miles and down to
approximately 1800.

supermoto bikes. Higher traction and corner grip also in wet, given by
an innovative and optimized tread pattern. Enhanced bike control, high
speed stability and quick warm up thanks to the new silica compound and
a new profile.
