I recently purchased my first bike a ninja 250, and i am very satisfied. However, i have found that on occasion when i am down shifting to first it doesn't stick the first push and kinda springs back while i have the clutch in. just doesn't seem right, i could just not be pushing it hard enough tho?

I would suggest you to get fix it by bike repairing shop.

I have never used a ninja 250 before but my bike doesnt seem to "spring back". You should really go get that checked out. Does it make a noise when it springs back?
