Hovewer the best looking radial engined bike I`ve seen so far is the french Verdel from 1912.

However this longitudinally positioned engine may have a problem with heat, no. Jesse James version I think will promote even coolin of each cylinder.

I've half joking suggested that somebody should make a bike based on a rotary engine. I think somebody makes a replica for kitplanes, so might be doable. I've seen Mazda rotary powered bikes before, but this would take the cake! “WWI rotary engines had significant gyroscopic effect because the crankshaft was stationary and the whole engine mass rotated around the crank.”

The other side has oil pump, distributors, carbies, starter motors and all the other ugly bits...

These modern radial engines don't rotate and require low mass crank and flywheel assemblies due to the uniform distribution of reciprocating elements around the crank's 360 degrees of rotation. Hence, negligible gyroscopic effect. WWI rotary engines had significant gyroscopic effect because the crankshaft was stationary and the whole engine mass rotated around the crank.
