I know a hollow material can be stronger (i.e., a piston pin and its flex properties compared to a solid piece which bends). The only reason I recommended a machinist build a solid one is that it's easier for the machinist. Unless they have something that's the right ID and a close OD laying around -- in which case, a good bushing material could be an option.
Bent Axle ??!!
While I was in the shop working, I kept hearing a LOUD slamming noise and a bunch of laughter....... my 2 friends were jumping my TTR (totally stock)about 35-40ft, they were launching off of a cinder block with an old wooden slat shudder for a ramp !!!! If only I had a pic !!!
I had to put a quick end to that......I cant believe that bike didnt bust in two.!!
No bent axles (one of the guys wieghs 230lbs)!!! :scream:
Ask Jeremy Wilkey if you bump into him, he was watching in disbelief!!
That little bike is tough!!
Vic , I have to ask......whatever did you do to that bike to bend the axle??!!!
John- With friends like that........:) I probably jump some stuff that I shouldn't ,too. I will say that I've had the bike for over a year and it took this long for the axle to bend enough to be a problem. No other durabliity issues, yet.
