My brother had a monstrous Valkyrie 1800cc but when he rented a scooter once, he wiped out because he applied the front brake sharply, the front shocks had a lot of give, it was much lighter than what he was used to, and he flipped over! He seriously hurt his hand. Never laid down the Valkyrie once!
Here’s my riding partner on my bike… I’m not one to dress up dogs but on the bike one must have eye protection (plus she is fully harnessed).
