Does anyone have any info on this CB1?
Notice the "frame sliders" on the video.
Wonder how hard it would be to make something like this?
a local welder perhaps.

Wonder how well it would work?
CB1 Gururs....chime in.

Love the paint on that bike!  I know there was some discussion about frame sliders being a problem as some of the possible attachment points might break an engine mount.

humm...thats interesting cause the 919 has a similar situation, yet the mounts work just fine and no engine mounting-point breakage.

I think because the 919's frame comes down on the outside of the engine mounts, the frame slider actually attaches to the frame, not the engine mount.  So the frame takes the brunt of any impact.  The CB1's frame comes down on the inside of the engine mounts, so the mount takes the hit.  There are images somewhere of broken engine mounts on the CB1 because of this.

Look at Peter Long (Long time "no pun" intended, CB1 enthusiast AND racer). He has proven track knowledge that 'his' frame sliders work.
Read the FB post discussion.

Also, trying to get Peter to send/post up some photos (nice ones Peter not them 1970's grainy-blurry ones) of how his were attached.

So I didn't notice because of all the blacked out parts on that bike, but it has an extra steel bar going from frame slider to frame slider for extra support.  I've never seen those before, but does make sense because that's what the CB1 needs to prevent engine mount damage.

EXACTLY!......I think this little contraption makes sense. We already have a race fellow (Peter) that has tried and true tested frame sliders multiple times WITH success. Now if I can only get him to send me some nicer images of his bike WITHOUT the farings so's I can see how those pups are bolted on. (Peter? you reading this)?
