Question

When i was young i had a dirtbike with 4gears that i had to switch but no clutch whats up with that

Answer 1

Several manufacturers, especially Honda, made them to make riding easier to learn and enjoy.

The clutch was semi-automatic with a feature built in the shift cam to disengage the clutch during shifts, but allowed automatic operation from a stop.

I had a Honda 50 Step-thru and a Trail 55 that had that feature.

Lifan (China) makes clones of the Honda engines but I have no experience with them personally.

Answer 2

Semi-automatics are still made today.

Most ATVs are semi automatic - 4-5 speed transmission (shift gears) with an automatic clutch.

You've been away from motorcycles to long.

2008 & 2009 Yamaha TT-R50E - 3 speed (shift gears) automatic clutch.

Answer 4

what are you asking.

Answer 5

I have an old Honda Passport scooter with that type of transmission, except it only has 3 gears. There's a centrifugal clutch, like on a go-kart, that engages when you accellerate and disengages when youlet off the gas to shift.

Answer 6

They made some bikes with an automatic clutch you can still find them around but they are mostly on the made in China bikes I don't know if Honda or any of the other good bikes still produce them or not

Answer 7

it's called a 'semi-automatic'... you'l find them on alot of kids bikes... as they can and often do have difficulty mastering clutch control at that young of an age.  

Answer 8

Honda 90 or 110. Centrifugal clutch
