Description
Fits: Arctic Leopard XE Pro S, Arctic Leopard XE Pro S Enduro, Arctic Leopard XE Pro R
Linkage required: the stock Arctic Leopard linkage will not work with the R38. You need the TMB R38 linkage, sold separately. Message us and we will add it to your order.
The R38 brings the internal architecture of the larger Sirris R46 to compact e-motos: the same 16 mm hollow shaft, base-valve cavity and internal floating piston, plus a new 2SC two-stage compression system with independent low- and high-speed adjustment. It is tuned for each bike model and designed to pair with Sirris F43 CMX forks.
