The Neon Machine

RIVA Racing published this build and this parts list. Everything on this page is theirs. Nobody here has ridden it, measured it, or checked it against a rulebook.

What the builder claims

Quoted from RIVA Racing's page. Not measured here, and not reproducible without knowing the conditions, which are mostly not published.

Power: 350 horsepower RIVA's wording is "a reliable 350 horsepower". The measurement point and the fuel are not stated.
Top speed: 81 mph RIVA says each unit is hand built and water tested to confirm performance. That is RIVA testing its own build, which is worth more than an untested claim and is not an independent measurement.

What this build shows

Worth reading beside the Yamaha GP1800R build in this archive, because the two are the same idea on different platforms and the parts lists rhyme: a tuning licence, a power filter, a catch can, a charge cooling upgrade, a billet fuel rail, a rear exhaust, then sponsons, steering and bars. Both reach the same quoted 350 horsepower. Neither list includes an impeller, which on this Sea-Doo is the one obvious absence next to the Yamaha's Solas Concord.

What this page does not tell you

Whether any of it is legal in your class. A builder describing its own product, including by a class name, is not a check against a rulebook. Class legality holds the checks that name a section and a person.

Whether it would do the same on your machine. A quoted top speed is one builder's result on one craft, usually without the conditions, the rider weight or the fuel.
