hi,
I was riding today and the bike won't speed up I even shifted gears

Isn't that a problem with all 250's? :lmao:

That said, if you're shifting up too early RPM-wise, yes the bike would definitely lug. I forget what the CBR250's power-band is, but you should familiarize yourself with it and learn to shift appropriately -- this will help tremendously with acceleration, smooth shifting and overall control of your bike.

Its some where around 6-8000 RPM I think.

Sounds like a burnt/wrecked clutch to me, and depending on how the bike was shifted, could theoretically be caused by shifting into too high of a gear when at high RPM (and using the clutch to bring down the RPM after the shift). If this was the case, then I doubt Honda would cover it under warranty, as the clutch is considered a wear item unless it was defective from the factory.

As for the meat of the powerband, like Bagel09 said it is around 6,000rpm-8,500rpm or so on the CBR250R. If I'm just cruising/riding in the city I'll shift around 5,000 or 5,5000 or so, but when I'm on the 401 or up in the twisties I normally take it to either 9,000rpm or into the red (but before the limiter) and try to rev-match all my shifts up and down.

hi
ya i think that was the problem the clutch and the gears im not sure how to explain it but im happy it is fixed. ya i need to make sure i rev it to high rpm before going to third and up gears.

I'm not sure that actually makes sense...? Someone who knows better can you please explain if this would be possible. I haven't heard of gears getting "messed up", maybe the clutch slipping and/or cable needing adjustment... which actually might make sense in this case...

Ya that was def my problem i was afraid to red line it when shifting when i should have been red lining it and shifting but since i ride in the city and there is a lot of sudden changes i have to be more careful with the shifting.
