Why does honda derbi aprillia ect ect carry on with GP250 racing they don't make 250 road bikes any more.Why don't they bring in tuned no holes bared 600's surley that would sell more bikes.i know you have supersport 600's but are they not limited to how much tuning can be done?Also why did thay scrap 500 gp racing?is it perhaps that they reached a peak of development at around 160-170BHP if they brought out a 750 stroker would that not be as fast or faster than todays 4T's.
