I know some guys on here have done it - but is there a difference between MSV and No Limits in terms of how it works? Assuming you have to pay something extra to cover the second bike? Or do they just give you a second set of stickers and tell you to get both noise tested?
No real difference with who the organiser is, there's nothing extra to pay. After all, you can't ride them both at the same time. Just decide which bike you're going to start the day on and worry about stickers and noise testing for the 2nd bike later (or in many cases not at all).
