Generous 20 amp rating exceeds the requirements of 10 amp, 16 amp and 14.5 amp two and three wire stators commonly used on British bikes. 

Heavier wire connections are extra long (60 cm) in two sleeves so you can route the wires and connect them exactly as you wish.

Smaller in size makes fitting possible in tight locations under the seat or behind side panels. Cool running so you can hide it away!

Why muck around with hot unreliable regulators that waste over 20 watts of precious power when you can have the latest!
