I have used it on Piaggio, Honda, Suzuki and Kymco scooters and on Yamaha & Honda motorcycles....with good results. Recommend the pump spray and soft 2" or 3" paint brush to work it into tight areas.
I would have to leave one bike unprotected for a damp, salty winter or two to give a better comparison.
So, I make this effort with the product as it seems the most highly recommended.
It is time consuming and messy.....and has an odor for a few rides as it cooks. But I find that to be a reassuring smell.
