Set of 6 (23x18mm) roller weight weights from Prima. These high-quality HD [Heavy Duty] weights not only perform very well as
a stock weight replacement, but also show their true potential in high-end engines. During production, the inner ring is
carefully knurled and only after this is it bonded with the plastic. This prevents the weight material from separating from
the inner ring under temperature fluctuations, which usually happens with cheaper weights. The high PTFE content in the outer
material provides good self-lubrication and durability and the characteristics of the Teflon provide smooth Variator shifting.
Very good value for money and one of the most durable weight components in our range.
We highly recommend that you begin by upgrading the variator roller weights before engaging in any performance upgrades. This is the simplest of upgrades and the least expensive. This is a minimal investment and offers a maximum return.
The main rule for tuning variators is the lighter the roller the more rpm’s are needed to push the rolls outwards through centrifugal motion to set the gear change in motion. Heavier roller weights need lower rpm’s to start moving.
Heavier roller weights = slower take-off speed, more acceleration = higher maximum speed.
Lighter roller weights = faster take-off speed, less acceleration = lower achievable speed.
The right balance is an individual choice since a scooter racer will want heavier weights to achieve a higher overall speed so that they might be faster at full throttle. For daily use a rider might prefer lighter weights for more power to take off faster at stop light.
