I spoke to the guys at my local tyre place, who are all bikers by the way,and they advised me that due to the power and weight of a sport 250 machine they would never (unless you are track daying it) really get that hot....or even warm and recommended that a set of the softest compound were the best option and his recommendation were Bridgestones.

Yes, and no. What you've been told is a little ambiguous.

Ideally you want an H rated tyre. The speed rating [up to 130mph/210kmh] is specifically designed for small lightweight sports bikes like the NSR/TZR/RGV, and I can assure you, get well up to optimum temperature on spirited rides, particularly in summer! Bridgestone make the 090 in H rating.

However, for example, you could get the softest 110-70-ZR17, and find it doesn't get up to full operating temperature, as it's rated for 150mph+. Again though, there are exceptions to every rule. Certain suspension setup and riding style can work a front ZR tyre quite hard... so I'm told!
