You won't find one for a R3T... we are so few.
 
This Daylong seat is the best seat I have ever had . I have ridden over 13 hrs in one day
and I get off the bike like my ass has just Started the trip. Can’t say the same about my neck.
No matter what bike I end up with in the future I will be putting a Russell seat on it.
I didn’t think much of the sunbrella material at first and thought I would get it recovered
but it also has exceeded my expectation.
Pete next time I see you I am going to give you a big kiss.
