H1 or H2 frame wanted - probably ...

Postby H2R » Wed Jul 11, 2018 5:46 pm

It's a long story, but I'm now looking for either an H1 or H2 frame. Doesn't need to be mint or anything like that, damaged will do, up to a point!

Apart from all the road bike brackety bits, what are the differences between H1 and H2 main frame and subframe tube layouts? I know about the swinging arms ...

Thanks

Stephen

The H1 frame is a better design in that the top tubes loop around the outside of the down tubes rather than inside them. So they are wider apart and and make for a stiffer headstock, less resistant to twist. H1 is also a bit smaller. H1 has the front engine mounts bolted direct engine to frame rather than with the triangular plates.

Kh500 frame is probably best for stiffness as it also has lots of extra bracing as standard Thumbs Up

I'm sure I have a H1F frame, but without paperwork, only problem is I'm a bit too far away

I will also add that the later 500 frames as well as being stiffer, they also have a 3 degree steeper steering head angle which is what you would want I think.
This applies to the H1E onwards having the same 39 degrees as all H2's.
The drum brake models are 42 degrees and strangely H1B and H1D are 40 degrees.

The same steering head angle as H2 is an attraction, thanks for bringing it to my attention!
