I just spent most of the afternoon installing the cruise control package they have. Took about 4 hours of cautious (read slow) time to install. Their instructions are amazing. Cover every last detail and make it foolproof (read even I got it right). It is an expensive package but so complete that all you need are the tools. If you want to see the installation the have the manual on their site, it has all the pictures. Already took a little test drive and it works perfectly.
it's stupid that Triumph markets a "Touring" model but refuses to offer a factory cruise control for it. Their primary marketing target, the Road King, has had a cruise for years.
