man nice rides!! but man i'll give an advise to ride 'em carefully..i'm telling this by my personal experience..my friend had a kawasaki 750 street bike but man it used to run like, i would rather say fly like hell..n the moment i used to grab its handles, something used to happen to me..i just couldnt control myself n i used to test it to limits...but once when i was doing some 170+ n suddenly i realized that the road ahead was not enough for me to stop it, i pressed the brake pedal n its rear wheel locked (infact i was not a very good rider thats y didnt bother to apply the front brakes aswell)...man thats the ugliest thing which can ever happen to u when riding a bike...the bike had a big skid but fortunately before it could hit the road i released the brakes n it got stable again(n i was not even wearing a helmet)...i believe i cheated death that day..i didnt tell my friend wat happened but i got so much afraid that i never took his bike for a ride again coz i thought death wont spare me again...i was young at that time like u people (jawani ka josh thaa) but i learnt my lesson well..so my dear brother never put these untrustworthy machines to the limit...Life is very precious!
