I do really like mys Speedmaster.The other week I took the oldest grandson now 15 for a ride.He is taller than me. Yes if you are going to ride two up more power and room would be nice.Test rode some Victorys yesterday.They had a demo day.Nice but I do know if I go to buy I will test the Thunderbird again and several others.I did like the solid feel of the Victory and the Kingpin did ride nice and felt really good.The power was very nice, 106" ,it should have a lot of power.The trans was clunky.Thunderbird when I rode one was very nice shifting.On the other hand do you mean Triumph will change the Speedmaster into the Thunderbird platform and size? If anything I hope they leave the Speedmaster the same physical size and up the cc's to maybe a 1200cc with more hp & torque so it would not require so many mods to make them run like they should have from the factory.Just my opionion.
