Downshifted by itself.

gyazbek · 10-15-2010, 12:38 PM

Hello! Today as I was driving back from school, I accelerated to merge into traffic, shifted into second, third, and then as I am about to take a turn the bike downshifts to second causing it to over rev and the rear wheel to skid. Would there be any reason why the bike might have down shifted? (I was ready to shift into 4th before the turn, and that scarred me because my foot was positioned under the gear lever, so I didn't push it down.)

Thanks ahead of time!

That happened to me once during some hasty up-shifting , luckily on a straightaway. It hung onto 3rd for a second or two and then just slipped back into 2nd. I put it down to being a bit too light and quick on the lever. Maybe I need an oil change?

That was exactly my situation!! Upon merging into traffic I shifted as if I was on a CBR 1000

, guess it wasn't a good idea!

I've had that happen to me on my Kat before. Motorcycles just have funky transmissions. If it doesn't lock into the gear all the way, I suppose it can just happen occasionally.

Newer bikes will sometimes do that. But one should always be sure to do a more positive shift to avoid a false neutral or an unwanted shift.
Years ago I had a Suzuki SP 370 with a truly interesting gear box. I could catch a false neutral between all the gears above neutral any time I wanted. A little more omph to the shift and it was in gear every time. That was the only good part of the bike regretfully.
