INTERNATIONAL DEALER NEWS - AUGUST/SEPTEMBER 2018
SIP Performance
ignitions for Vespa
and Lambretta models
German
specialist
SIP
Scootershop welcomed over
2,000 visitors to their state-of-
the-art 6,000 sq m facility at
Landsberg, Germany, in early May.
They welcomed enthusiasts from
as far afield as Malta (six scooter
riders who made the whole
journey on their Vespas) as well as
Switzerland, Austria, Italy and
England.
Highlights included a Vespa Club
information booth, rare scooter
models from the 1950s and a
used scooters and parts and
accessories market, and the
company plans to welcome
visitors again in May 2019.
Recent new products from SIP
include these new SIP
Performance ignitions for Vespa
models (Lambretta ignitions
coming soon). Manufactured
with the assistance of VAPE, a
major European producer, SIP’s
Ralf Jodl says that the electrical
functions of these “high-end
ignition systems are
representative of state-of-the-art
modern technology. Due to the
eight coils included on the
stator-plate, enough power (110
W) is created at tick-over revs to
fully illuminate the Vespa’s
lighting.
“We have both AC and DC
versions available, and we
recommend the DC type if you
wish to pow er digital
components such as the SIP
speedometer, or you require a
high battery loading charge. The
CDI module is available as a
‘Road’ version with a static
ignition point, similar to the
original item, or as a ‘Sport’
version that includes a variable
ignition point which advances at
low revs.
“This increases the available
torque - especially at the lower
end - and the ignition point is
then gradually retarded as the
rpm rises into the power-band.
This also helps reduce the
combustion temperature while
simultaneously providing an
increased rev-range”.
The pick-up on the stator-plate is
split into two and arranged on
top of one another instead of
next to each other, as with the
original design. This eliminates
the possibility of false
positioning during the initial set-
up “due to the sloppy
manufacturing tolerances
included on many Vespa engine
casings, crankshafts, stator-
plates and flywheels. The exact
ignition point is clearly marked
with a precise line on both the
flywheel and stator-plate, which
allows exact positioning during
assembly and makes a strobe-
lamp set-up unnecessary”.
Jodl says that one of the most
important advances achieved is
the production of the
fly/fanwheel unit as a single
component - avoiding a riveted
inner mounting-cone and an
uneven rotation. He says this
greatly reduces engine vibration
while also noticeably extending
the working life of the flywheel
side crankshaft bearing.
The precisely balanced one-
piece, twelve-finned fanwheel is
CNC-machined from solid
