I' ve noticed a noticeable clunk when I drop to first while coming to a stop clutch in. I am in the break in period.... Bike has under 300 km. Is this normal? I guess I am thinking it could be smoother/quieter. Being a newbie rider I can't compare to past bike experience. So... Calling out to fellow riders :)

Cheers

i used to have the clunk when i first got my bike,but only when i was downshifting to 1st gear at speeds of 15mph and higher..,im a lil past 2000miles now,does it still clunk if you are at lower MPH lets say 8mph?

i dont notice anymore clunking

Motorcycle gearboxes almost always have clunks and other noises. But as you become more familiar with the bike you will begin to notice at what speeds and RPMs the gearbox prefers to be shifted at, both up and down the gears.

I've been able to go up through all the gears with just a snick at each change and then the next time through there might be a clunk if I miss the perfect speed, amount of clutch activation or RPM level. It's all a matter of syncing up the engine speed with the rotational speed of the front sprocket shaft. The rider becomes the greatest syncro between those two spins and the better you can sync them before releasing the clutch lever, the smoother your shifts will be. Try giving the throttle a blip after you pull in the clutch and before you shift from 2nd to 1st. I do this between 3rd and 2nd to try and avoid the clunk there. I just wait until I am almost at a stop before shifting to 1st to avoid that thunk.

You may need to take up a bit of slack in the clutch cable. A clunk could indicate that there is still a little to much friction between the clutch plates when you pull the clutch lever in.
Don't over do it though as otherwise you may have the clutch plates not contacting perfectly while the clutch lever is completely out.

I appreciate all the replies, great forum! Yes, the clunk...thuNk is there at low speed. It doesnt happen from 3 to 2.... But just as I crawl to stop ' clutch engaged and push down to 1. For now I'll improve shift finesse and monitor it.

Love the bike though! Black with abs:)
