The V1 is not specifically designed for motorcycles. Neither is my Escort.
I have a rain proof cover that I got from Legal Speeding for my Escort. Unfortunately, they don'y sell them anymore (so I bought two). I've been on Rennlist for about seven years also and I must say, there is a lot of BS on that board (IMS bearing)
