These include the Kinetic Luna (older), TVS 50 and Bajaj Sunny. Here the clutch is used precisely for the reasons above..<BR/><BR/>Once engaged the vehicle speeds are in direct proportion of the engine speed as they have only one ratio (fixed down by a chain and sprocket). Hence the engine is tuned to give a compromise of both initial torque and high speed performance. That is why people complain of either the pick up of their fixed speed vehicles of the top end performance.<BR/><BR/>Incidentally the centrifugal clutch was also used in the (manual geared) Hero Honda Street.Gliffordhttps://www.blogger.com/profile/06773633458648790579noreply@blogger.comtag:blogger.com,1999:blog-21612698.post-34242742070033442952007-08-14T23:22:00.000+05:302007-08-14T23:22:00.000+05:30Whoops! Looks like i provoked a big post. No serio...Whoops! Looks like i provoked a big post. No seriously, I thought we referred to CVTs as varios and vice-versa.<BR/><BR/>Someone once told me that the transmission in the Kinetic Honda has the cone-belt system, which lead me to believe that it had a very efficient CVT system. That's why it was considered miles ahead of regular centrifugal clutches like on the sunny and other crap.<BR/><BR/>can you confirm the kinetic had only a centrifugal clutch and NOT the belt-cone thingy ?Anonymousnoreply@blogger.com
