I use the straps, but just remember, when you lower the front and still have a full moving suspension you may bottom out the fairing.
Only if you loosen them. DO NOT ride on the street with the fork strapped down. The whole idea of suspension is to keep the tires in contact with the ground - going straight it doesn't matter much (until you have to brake and it's a bit bumpy) but hit bumps in a turn with no suspension travel and you might very well crash.Can you leave the straps on for everyday riding
just casual riding
