I don't think it should be doing this... I downshifted to first gear at about 15 mph and it shuttered badly so I pulled the clutch back in. It's done this twice now. Should I take it in for warranty or could it still be breaking in?

Bike has 181 miles no other problems that I'm aware of.

Hi:

(if you're an experienced rider and I misunderstood what you were trying to say, apologies up front)

15mph is sorta fast for first gear, especially on the CBR250 where the first couple of gears are kind of low. If you were coasting at 15 with the engine at idle and let the clutch out I would expect some shuddering. To avoid it, throttle the engine up before easing the clutch out..

Clutch slipping is usually most noticable in high torque loads - e.g. rolling on the throttle in 3rd gear from, say 2000 rpm.

All that having been said, just noted that your Audi probably has a straight drive - if that's true, then you already know what i said, so take it to the dealer and show him.

I just did it like I do the other gears, I def try to rev match on down shifts like I do in the Audi.

Just felt like the little engine shouldn't be enough resistance to ever make a clutch slip on a downshift. Though the RX-8 I used to have would engine brake so hard the tires would "lock up" or act like it if you know what I mean.

I'll add that every time I am downshifting it only because I will need the gear for the turn I am about to make. Most of the time it's at 3-5k RPM's when the down shift is complete.

It was actually the tire screeching turns out. I don't need to get lessons for that........ I was used to my friends 400EX, 2 tires meant I could do that on the street. Make mistake, learn from it, move on. Way better then anything anyone can teach you.

As for what Dave is saying, I always down shift until I hit 2nd (now I go to neutral from 2nd until around 5 mph)

I do this for a couple reasons, not only just to slow down but also so that I can keep track of the gears I am in w/o keeping a head count on it at all times.

I think a basic or advanced motorcycle safety class would always be a good thing.

I was eventually going to take the one that gets you certified for the license rather then just try to get it at the dmv. I'm told it's 100x easier. I have like 10 people at home giving me constant tips anyways though, learned a few things like if you turn the handle half a degree in the opposite direction of your turn it helps you lean the bike faster into the turn you are going into (helped me a ton for linking turns on curvy roads)
