Just got an email that Corbin is making a Tall boy seat for the m109r, isn't that a batch…. Got my front and back set this year and know they are making a Tall boy seat. Talk to a represented today and they must have some guy trying it out on his bike and said it is much better than their original mode. If it can set me back 2 to 3 inches I will put my driver's seat up for sale (heat built in). He told me that they could mode my seat to make it set back further but at 145.00 and me shipping it I may upgrade. If any one here's more about the Tall boy seat keep I posted. I want to know is it worth it.
