I know what both terms mean (although I'm sure the OP meant "brake specific fuel consumption"!)
But, this information is not easy to come by. It will also vary depending on RPM and engine load. There is no fixed number for either one. There is a performance map, with RPM on one axis and engine load (normally referred to in terms of BMEP - "brake mean effective pressure") on the other, with curves showing the BSFC at each point. Takes a lot of dyno testing to obtain this.
Helibars, MRA screen, Ohlins damper, reversed shift pattern, sorted suspension, braided lines, Michelin Pilot Power, all else stock 'coz it's fast enough!
