1. P6 Sport with UA 19 S carb, ∅32-exhaust cylinder, 14T
1. P6 Super Sport UB 20 carb ∅35 cyl, Record head, 14T
2. P6 Super Sport
Same as P4S: The bore and stroke remain the same, 38.8 x 42. The cylinder base diameter and cylinder studs remained the same, 44 and M6 x 110 spaced 40 x 40. The head, cylinder and piston are the same as P4S. Compression ratio 9 to 1.
P6 changes: The center width of the crankshaft, between the crank bearings, increased from 32mm on the P4, to 36mm on the P6. The cases changed from P4 rounded to P6 angular.
2. 1970-77 Minarelli P6S, P6-4
P6S has pedals and a 6-speed foot-shift transmission. It’s the same as ’69-77 P6 Normal except for pedals.
P6-4 has pedals and a 4-speed foot-shift transmission that is convertible to 6-speed. It’s a P6S with two of the gears missing.

Note 1. The pinion gear nut has M9-1.0 thread and is 12mm long. Part of the 12mm length is round with 12 or 13mm diameter. The other part of the length is hex 14.
Note 2: The original Dellorto SHA 14/12 carb had a 56 jet, 18 clamp sleeve and a 10236 air cover. The replacement is a genuine Dellorto SHA 14/12 with a 56 jet, 18 clamp sleeve, and no air cover. See Dellorto SHA14 for carb parts and info.
Note 3: The original Ducati 31.02.39 magneto had a 6V 18w lights coil and an internal spark coil. See Ducati magnetos for parts and info.

3. P ’74-75 P6-75 74.7cc (46.5 x 44) on Indian ME76, MX76
SP6 Changes: At the start of the 1970’s the SP6, aka P6 Competizione, was the racing version of the P6. The SP6 later became a 50cc sport bike engine used by Fantic and others. It had a steel-sleeved aluminum cylinder instead of all cast iron. The engine cases had a different cylinder stud spacing, 48×48 instead of 40×40, and a different case bore, 47mm instead of 44. That allowed for bigger transfer ports and the option of a bigger bore.
