Big biker rally in Tallinn this spring. Where to rent a motorcycle there?

[Saruman]

There is a major international biker rally happening in Tallinn this spring and I am seriously thinking about going. Done plenty of domestic rallies across the States but never anything on this scale with riders coming in from all over Europe. Want to actually ride with the crowd there, not just show up as a spectator. Anyone know where to sort out a decent motorcycle rental in Tallinn?
