Hey Karl,If I knew how to post a picture I'd show one of my '09 T100 with it's "Day Long Saddle". I use my Bonnie a number of times each year for touring (I'm an ex BMW K1200 LT and Gold Wing GL 1800 rider) and a comfortable long distance, all day saddle is very important to me. I've ridden over 400 mile days and at age 67 my knees and shoulders give out long before my bottom!
Doesn't look out of place though it's obvious it's not a stock seat.
Thanks. Delicate bottom these days and needed all the help I could get! Nothing is a panacea on this bike but I rode a pal's Sargent before ordering mine and benefited from his experience before ordering mine. It took him three tries to get exactly what he wanted which was costly. Mine is less dished in the front that his. You can see the differences here but anything is possible. Cost is ~ $350 - $400 depending on options. My seat piping is thinner than my pal's. http://www.triumphrat.net/members/albums/48473-lambroving/Great looking seat, lambroving... a nice touch to your already classic looking T100.
The MotoTwin seat from Mike at BellaCorse "sort of" matches the gray top seats on my '66 Bonnies.Nice looking seat! Mine is the same in all black on post #8. I really like the old style logo on the back. I was scared to get the two tone, but yours sure does look great.
