some newer bikes with precision gears, may be able to shift to a higher gear with no clutch, the problem is you can also break expensive teeth and set yourself up for future problems, the clutch is not there just to give you something to do, it serves a pourpose. And the better you take care of the bike, the longer it will last. I have ridden without a clutch its not the smartest thing to do, but hey, thats fine, do what ever makes you happy. If driving down to have the cases split so they can rebuild your tranny is part of the deal, well I guess thats the way it goes, sometimes your a winner, and sometimes the mechanic is.

Some two strokes can be downshifted during deceleration without using the clutch, and without doing any tranny damage. However, it takes a light touch and a good ear to know when you're at the correct rpm for a given gear. No way to upshift without the clutch without doing damage.
No four stroke can be shifted without the clutch without causing some tranny wear and tear.
The reason is - some two strokes make all their power in the upper rpm range, and develop mainly horsepower with very low torque.
All four strokes (and some two strokes) develop torque at a very low rpm range, and continue developing it up into higher rpm range, way after horsepower kicks in.
This means these engines are making power - and putting a load to the gears - at any rpm above stall speed.
And, if there is power to the gear, you need to 'unload' it before you shift, or you will damage the shift forks and the gears. The clutch is the way to 'unload' the gears before shifting.
Yes, pro riders do shift without the clutch (their engines get rebuild/replaced every race). I know there are some folks out there who have ridden for years without using the clutch, and brag about it to everyone they know - what they've got is dumb luck and a tranny with many problems that's just waiting to fail.

Look unless you are (use the clutch)prepared to spend a lot of money or learn (use the clutch)how to rebuild trans/motors/clutches etc use the dang clutch. If you're losing a race by "SECONDS" ...trust me it's not the clutch that's (use the clutch)causing it. It's horsepower, skill, experience, weight, fuel, engine size, track, climate or a (use the clutch)hundred other things. I raced for about 15 years and knew guys that didn't eat the day of the race cause they didn't want to (use the clutch)have any extra weight. STUPID! Now their bike had energy but they didn't. By the way did I tell you to USE the CLUTCH!
Safe and Happy riding dude!

Yes you should use the clutch unless you have the money to rebuild your bike every 100 hrs of riding or so. Th other guy is right the pros don't always use the clutch as to not lose secs. in a race. They also have factory sponsors that allow them to have the bike rebuilt after each race, something I am sure your not prepared to do. Good luck and use the clutch.

That is totally dependent on a lot of factors.....on my very old 1977 Maico 440cc I can up shift without clutch nearly WOT, yet I prefer to downshift with the clutch to kep from braking the rear wheel loose(unless I want to).
On my bike the trans is extremely durable, yet the clutch is a bit fragile compared to bikes of the same era. Anyway, most mx schools will teach you to clutch it out of every turn these days.
You must ride lot to begin to feel when you can pop a tranny in on the synchros-then you should decide to adapt your style to what is most effective for you. nearly 20 years of racing, most shifting was clutchless, and not one trans failure, either Japanese or European bikes.

No. In fact, the "pros" don't use the clutch but to get started. Matching gears in a syncromesh trans is the way to go.

Bad for the tranny??...Yes
If ya got the money and don't mind rebuilding your tranny every now and then.....obviously no problem!!
Your wallet and schedule will decide what you should do.
