very rare and highly sought after NOS solo engine!! these were rescued from the depths of a trash barn somewhere in ohio, wrapped in ski masks for protection from the harsh elements.

it's almost 2021 and we're all about to die, throw that vespa in the trash and toss your derbi into the baler. it's time to try something new and exciting. what's more exciting than a derbi you may ask? WATER COOLED SOLO DUH.

the water sits in the cylinder

these are actually mega rippers tho, they came with like 8mm bings to restrict them cause they rip too hard. hack a different intake on there and run a 15mm sha to let it breathe. watch out for the cops tho don't let em catch u doin 100 on the turnpike.

it run on water

uses minarelli sized exhausts!! we slapped an ev turbo on ours and it bolted right on.

your HPI is so tired of being on your dumb maxi e50 engine, put it on this instead

pro tip! pull the og clutch side seal cuz it uses some weird clutch tech and use a 15 x 35 x 7 seal. then just file a vespa single speed rear pulley a little and voila! you have a ripper clutchless motor. extra points if you combine this with a clutch pulley and mount it on a french bike.

this shim fits perfecto for using SHA carbs on this lil intake. They actually seem to fit perfecto at the normal solo operating angle in place of the usual 10mm carb.

what will you use your solo engine for? railcart? rc plane? trolling motor?

solo = so-long slow ass derbi
