70: Pure racing-…. ! The LeoVince Scoot
“70”; the number indicating the technical destination of this product,
for supercharged 70 cc scooter engines which are specifically used for
competition racing and are therefore not homologated for road use. A
special series, which constitutes an important stage in the preparation
of a racing engine. The expansion chamber is sold without any added
volcanic mass kit, to allow technicians to regulate the bike according to
the actual circuit conditions. The expansion chamber itself is of
enlarged size, with a cone/counter cone structure, and made totally of
stainless steel for the first time using craft workmanship and visible
TIG-welding. The silencer of the system features a stainless steel
interior with titanium skin. The attachment of the header pipes to the
cylinder is by means of a screwed flange together with two springs used
to reduce the vibrations level and the danger of breakage under extreme
conditions of use. The clear aim of the exhaust being to improve
performance at the highest speeds.
