You mean that 1960 dry clutch that Ducati uses is 2014 technology? Maybe you have a Monster with the wet clutch. I had both a newer Multistrada with a dry clutch and a brand new Hypermotard 796 with a wet clutch.....and believe me neither one came close to "2014 JAPANESE technology.My new liquid has the same whining noise starting with third gear. Spending all that money and then having the whining noise is quite disappointing. We are in 2014 technology and still having the noise. hopefully somebody with top end mechanical knowledge can help ease my concern. I am at the point where I don't enjoy it. Is there a solution? I also have a Ducati and the tranny is completely quiet. Understanding mine is not broke in (20miles), will it go away over time? Help!
I have a Ducati with a wet clutch. We are losing the focus of my thread. It's not the clutch. It's an obnoxious whine when shifting into 3rd gear. Very noticeable! I thought with 2014 technology that these problems would be worked out by now. I was using the Ducati and every other motorcycle I have owned, that it doesn't need to happen. I was looking for some help as will I have to live with it or is there some solution that people smarter than me have found. Something to quiet it down to make the bike more enjoyable to ride instead of putting ear plugs in on a new bike as a previous member said he does. That's what I meant by 2014 technology.You mean that 1960 dry clutch that Ducati uses is 2014 technology? Maybe you have a Monster with the wet clutch.

i'm not aware of any motorcycles that use helical gears in their transmissions, every one i've seen uses straight cut gears. it's a packaging issue, even on bikes which are basically 2-wheeled cars (honda gold wing). on a bike there simply isn't room (or rather, it's not desirable to make the room) for a massive transmission case which would be necessary to handle the side thrust loads created by helical gears. so keep it small, simple, inexpensive and easy to manufacture by using straight cut gears. gear whine is just what we put up with so bikes don't end up twice as wide and 150 pounds heavier than necessary.One quick Google search provided me with the following link: Straight cut gears vs helical | Automotive Thinker - Discussing the finer points of automobiles
Though it does not explicitly mention motorcycles, I'm sure the logic behind it is the same. My take on the article, straight cut gears are used for additional 'thrust' (as the article refers to it) and transmission longevity. Maybe with the amount of torque the engine produces Yamaha used straight cut gears to save expense when it came to transmission design.
I don't know much about motorcycle transmissions, hence my google search. But either way, I've always thought the whine from straight cut gears sounded cool. Maybe I just watch too many car videos on YouTube.i'm not aware of any motorcycles that use helical gears in their transmissions, every one i've seen uses straight cut gears. it's a packaging issue, even on bikes which are basically 2-wheeled cars (honda gold wing). on a bike there simply isn't room (or rather, it's not desirable to make the room) for a massive transmission case which would be necessary to handle the side thrust loads created by helical gears. so keep it small, simple, inexpensive and easy to manufacture by using straight cut gears. gear whine is just what we put up with so bikes don't end up twice as wide and 150 pounds heavier than necessary.
