Recently I looked at what it would take to make my Triumph twin competitive with the new BMW 1000 four. The big pistons in a 375 cc Truimph twin jug need to be moved up and down a lot longer distance than the tiny slug in an ittsy bittsy BMW 250 cc cylinder. The Triumph piston needs to go faster to do this and it must accelerate and decelerate much quicker.
Force = mass x acceleration. In practice, the tensile forces in rods and pistons are much greater in engines with comparatively long strokes and big pistons. Our twins simply cannot run with the four cylinder bikes. To do so, we would need to discover some extra strong metal, keep it secret, and build our rods and pistons out of it.
There are couple of things we can do, such as work on streamlining, keep the revs down and use lots of boost or nitro, or replace critical parts often so they do not fatigue and break. I am doing the streamlining route.
I'm sorry to see your motor. Hopefully you have a spare. Werner made good use of those leathers he bought from you. He set a record.
