I have fitted these to my beta evo 300 2t 2025. Where i ride there are ripples in the track from tractor tyres, original forks vibrated the bars, these m4 forks just glide. When I pull the front wheel up under power the front stays up longer, prob due to to lighter weight. I like them, I have guessed air pressure and damping, but like the way they react Have weighed original forks recon I have saved about 5lb from front, which is maybe the weight of a tyre. I put in all three spacer tokens, 2mm spacer needed for brake caliper, 6.5mm for disc side on the spindle, easily sourced from Internet.
