I own a 1992 CBR 250 RR Fireblade and with an experienced rider on board it can keep up with the likes of Yamaha R6's and Suzuki GSX-R 600's. With a little modification I found the bike to outperform new 250's and kill any other 250 RR's that try to go me! Great learner's bike and so much fun to belt up a mountain on!
