Mark,
I want to drive at normal road speeds - 60MPH, 70 MPH, even 80 MPH.
My bike reaches 60 OK. 65 takes awhile. 70 is rarely possible.
I would like 80 or more to be available, so overtaking is safer.
I ride FLATOUT where the road allows, that is because the bike is so slow!
There is NO problem with running at full power.  It is needed with any low powered bike.
If I had plenty of power I would not need to ride flatout!

I know a Japanese bike would give me the performance, but my desire is to have a classic British machine.
I do not have the physical strength to handle anything heavier than 300 lbs.
Cost is also a consideration. My riding is only local, its a problem thinking of anywhere to go!!
Mick

I have now bought a B44. first quick rides round the block.
It easily reaches 75/80 on the clock. Clock reads about 8 mph fast.
Must try to calibrate it.

My way is to use a satnav on the bike, or get someone in a car to drive at a set speed.
I note the speedo reading, then I stick thin adhesive strips on the speedo at each 10 mph point.
My C15 ss read 20 mph over at top speed, (85 at 65)

I now have a 17 tooth output sprocket fitted. Top speed is now 80 MPH, on a good day.

My c15 weighs 300lbs.
I cant manage anything heavier
Even some of the later 250 bikes are much heavier.

If you don't carry your tools and spares with you to loose some weight and perhaps fit a fairing, you might be able to get 90 out of the poor bike!

My old departed mate built a C15 Cafe Racer years ago, did 105. Don't know much about the build.

My C15 ss now runs on a 17 tooth sprocket, and 80 MPH true speed is attainable.
Checked against sat nav.

No JAPS!
I want a BSA, as I used to ride 55 years ago.
I want the fun of working on it, getting back on the road, and no expensive spending.
I now have a B25 to add to my C15.
