1300!

[Guess-Works.com]

1300's are 1275's

[mini77]

what about 1380cc?

[Spud_133]

I can't say that I've heard of a factory 1380, might be wrong though....

these are the only engine sizes that were produced by the factory for mini's...............1380 is an overbored 1275 as is 1293...1310...1330...1360...1400...and then you can bore and stroke a 1275 out to 1440....1460 etc plus all of the overbored sizes for the small bore engines...you can bore and stroke a 1275 out to over 1500 if your brave (or stupid) enough.

83mm................are you sure?...........does your engine have 'S' rods then?

people normally offset grind 1275 cranks to 84.3.

The 1098 cc engine is 83.72 mm stroke.
