I have used the Ventura system on my Speedmaster since 2003 and have found it to be an excellent choice for this style of bike. As Freedom mentioned Todd purchased the system for his 03 Speedtriple after having a look at mine in Nelson in 04. When he bought his Speedmaster he transferred the system onto that bike. The things that really sold me on the Ventura was the ability to mix and match bags, capacity, ease of removal, and the bikes width is not increased when the bags are mounted.
