TZR250-the reverse cylinder one, they could be mental fast with a few TZ250 bits. Suzuki GT500-superb big stroker, bloody strong engine too. Kawasaki KH500/KH750-you want mental?you got mental! Honda NSR250 MC28 Suzuki RG500-with Stan Stephens stage 3 of course.
Notice anything strange yet-like my choices are all strokers...........
New Yam R6, I saw one parked alongside a Gsxr1000 K5 a couple of days ago and to be honest it made the K5 look old fashioned! Especially from looking head on. Not fancied anything Jap for a long time till I saw this.
