Next year im going to buy my first motorcycle, a Kawasaki ZZ-R 250. I know friends who own it and they say its a good learners bike. my question is what bike would be suitable to buy afterwards?i´ll probably keep the 250 for a year or two, but what bike should i buy next?im very keen on the new Kawasaki ZZ-R 1200 but a friend who has the ZZ-R 600 said he doesn´t want to buy it because he doesnt think he could handle it. should i buy a 600, keep it for a while then see if i could handle the 1200? im 6 ft 2 and weigh 70kgs, am i too tall or small for any of these bikes? any replies would be greatly appreciated. Thanks
