Some great information, you must have  a large library.

1960 Super Rocket, owned since 1966, back on the road 2012 after being laid up for 29yrs.

I see they quote 52 bhp for the 8.25 to one engine. Gotta be what Phil Irving referred to as Brochure Horsepower!

Interesting that the 1961 USA West Coast cataogue gives 9:1 compression and no BHP figure.

minature horses vs clydesdales  *roll*
Throughout the sixties the BSA group machines (mainly the meriden subsidiary  *shh*) often quoted wildly varying claims for the same spec'd engines to show year on year performance increases.
What always amuses me is the earliest 40hp road rockets of 1954 through to the last 56.5hp (twin GP carb's) Spitfires and lightnings of the late sixties all have essentially an identical top speed (all were unfaired !)
And the lower tuned sports bikes definitely sweeter with less harshness
A good rider periodically checks all nuts and bolts with a spanner to see that they are tight - Instruction Manual for BSA B series, p46, para 2.
