France Equipement transmission kit - Honda 125 CR 1983-1984 alu

The different types of chain:

H = reinforced without O-ring
HG = gold reinforced without O-ring
KS and MS = hyper-reinforced without O-ring
MXZ = ultra-reinforced without O-ring
SO and KRO = reinforced with O type seals
FEX = super-reinforced with RX type seals
MFO = super-reinforced with XW type seals
GXW = ultra-reinforced with XW type seals
RO and GSV3 = ultra-reinforced 1 gold side with XW type seals
HRU = racing with Y type seals

O-ring (type O)

With a flat contact area to retain lubricant, the RK type O O-ring offers quiet, smooth, safe, efficient power transfer without the slightest friction. Always lubricated thanks to its flat contact area, the O-ring chain prevents all risks associated with use.

Seal type RX

Seen cut away, the RX joint is in the shape of an X, giving it an additional lubricant reservoir, reducing friction due to torsion, thus providing optimum performance under high stresses, as well as a long service life. service increased by 30% compared to that of ordinary O-ring chains.

Seal type XW

Ideal for high speed and high temperature use, the XW seal has 3 mating surfaces, 2 interior stabilizers and an advanced component of butadeine nitrite.
These features provide effective protection against wear due to friction at high speeds, against intense heat, against bending due to torsion.
Minimizing the risk of failure, the XW seal provides 50% longer service life than conventional O-ring chains.

Seal type Y (Ultra)

O-ring specifically designed for motocross and road circuits, the ultra-thin Y-seal is introduced into the space between the inner and outer plates.
Equal in weight to a seamless chain, it offers more efficient power transfer and incomparable heat resistance.
This model is ideal for new generations of racing motorcycles where lightness and available space are important factors.
