I'm trying to decide whether or not to brace a 72 H2 frame. Not sure what I plan on using for suspension at this point but not stock. This
is not a matching number bike so it will be built to ride, handle, and stop as best as a 72 H2 can with a lot of help. My first triple was the 75 Denco
replica that I built about 7 years ago and I braced the crap out of that thing. I worked really well compared to a stock late H1 and light years
better that a early H2. My question is, if I braced it like my old H1, well it be worth it? I followed this for my H1
My end result
) We did a couple of things that your Illustration says - Run a mig (in the day) welder over the factory welds, and use beefier engine mount bolts. Way back when, we bought the steering stem in for 25.5 degrees rake, and put 1" into a slightly braced swing-arm, the memory is fading, but it was inconclusive...... The answer to handling is proper set-up, and bolt-ons, (shocks, etc.) I don't personally think frame-bracing is needed on a triple frame, given all the other things you can do. Raced H1/H2's for 10 years or so, and riding here is all tight, twisty, bumpy back roads. I reckon the triples handle fine, but time has caught up with them when you look at modern frames, suspension, etc, (of course!)
