My husband (MrNickwiz) has a Renntec carrier on his Thruxton. There may be some photos in his gallery, but I'll let him know you'd like to see some. It's very good, I've ordered one for my Bonneville.
I know sofiaspin has one on his thrux - he has posted positive comments on it. I don't think he has posted any pics though.
No he has not but will try and do so. Mr Nickwiz might beat me to it. The positive is that it fits - which some were unsure about. Even Rentec had no idea. Some purists think it does not work the rear cowl, but you can remove the cowl
Here you go. Renntec rack fitted to my 07 Thruxton
It looks pretty good. can be removed quickly if you want though I leave mine on as I think it looks fine and adds practicality for an everyday biker like me.
