Customer evaluation for "Fork springs Set"
6 Nov 2021

Did I buy a new motorbike?

No! I just put these new fork springs in my 1985 R 80 Monolever. A big improvement: greater precision in cornering, no sudden sinking even after sudden braking and no hopping even on uneven backgrounds. Definitely a step forward: recommended.
