Pirelli are pleased to announce the availability of new sizes in the popular Diablo Rosso II Hyper-sport Radial Tyre, specifically designed for 250cc sports motorcycles.
The new 110/70R-17 54H and 140/70R-17 66H sizes were used as control tyre in the 2011 European Junior Cup on Ninja 250 as part of the World Superbike Championship.
Available now in Australia, these new Diablo Rosso II sizes are perfect for 250 riders looking for a sporty radial tyre for their bikes, upgrading from the normal X-Ply construction available as standard on most models.
With Zero degree steel belt construction, Enhanced Patch Technology (EPT, for a larger contact patch) and a host of other WSBK derived technology just like big brother Rosso II ZR, these new tyres allow a greater level of sports riding performance for the 250 market.
These new sizes are ideal for Honda CBR250R and RR, Ninja 250, VTR250 and many more.
Three further sizes will arrive June 2012 to further increase the "HR" range - 120/70R-17, 150/60R-17 and 160/60R-17.
-------------------------
One year later it seems the HR's have only just become more available here in 'Straya.
Pirelli Rep yesterday told me I can get the HR or R DR2 choices but cannot supply me SC1 (in the correct 110 size).
Racing on it next weekend so I'll let you know how it goes compared to 003 and SC SC1. Ive been thru enough of the fuckers to be able to be objective.
(my 250's seem to use more fronts than rears)

150 tyre on 3.5" rim = Chicken strips & tearing.
Ninja 250 & MC19(can someone clarify MC19?) have 3.5" rim
Ninja 300, MC22, & MC41 have a 4.0" rim but even so best to stay with 140 tyre.
