For the newish owners. I bought cartridge emulators for my front forks. I am no riding god but even I can notice the difference. My forks were completely standard before, but were in good condition with recent seals and new 10W oil. I have two VF500 bikes, one on original 16/18 wheels and one converted to 17 inch. I have now tried the emulators on both bikes and you can notice the difference on both. The main benefit is a feeling of stability (bike feels planted, like a big bike) especially at high speed. I got my set from DMr but a few companies do them. You need to change springs too. Highly recommended.
