Re: Time to give up?
The Nirve B-1 is a steel framed bike. I'm very surprised the frame cracked.
Would it be possible for you to post some closeup photos of your engine mounts, both front and rear? That would help us diagnose what might have caused the failures.
As for other problems you've had, what were they and what did you do to fix them?
We'd hate to see you give up even though I can understand your frustrations. Stick with it just a while and let's see if we can't talk you through some of the issues and get you back on the road with a little more reliability that you've had so far.
