Honda Spree and Elite 50 Forums

Found this in polini catalogue, looks like the replacement for the original 47mm vision/rapido kit meant for afo5e motors, part no. 119.0034. This one is meant for the honda sh50 and has a different exhaust angle, but it might still be a usable option for early elite and aero owners.

Part no. 119.0035
47mm big bore for honda sh50

Thought I'd put it up n see what everybody thinks.

Another pic of it. Kinda looks like a dio pipe would work on it, too? There's a mid-level pipe available for the sh50 and I think it would work w this bore on an afo5e case.

Pass over it. SH50 has a longer stroke than an AF05. 39.3mm vs 37.4 mm. Bore may fit 83, 84 Aero, the stroke matches that model, but stroke alone dont mean it works. Also, piston pin looks further from top.

Looks like you might be right, maybe w a different piston it would work.
I've got the polini bbk that's "out-of-production" (119.0034), and the guy I got it from says there's plenty in Stock in Europe, but who knows how long those will last.
