please fill out your location so we know where the bike is located
The value to someone who is prepared to sort out exactly what it is and what needs to be replaced to make it into a complete TR2 is fairly low. That's mainly because the bike is a hybrid of TR and street bike. It has some parts that appear to be original (brakes), some which are clearly modified (forks, seat, pipes) and other parts that don't belong on a TR (fenders, lights, controls). My first TD3 came in a similar package and I paid less than 500 for it because it was such a mongrel mix. I have not looked at TR prices in the US because there is so little market and it takes a long time to find a buyer and they are "collectors" who seem to want every part to be 110% original but in better than original condition. Complete but unrestored with all the correct parts fitted it would probably be worth 5-7k if you find a collector that wants one in original unmolested condition.It's value depends on how much of it is original TR2 and that is hard to determine based on the photos and information you have supplied. If it's an R3 engine with cast cylinder liners and R3 gearbox and clutch etc etc then it's worth basically whatever you can get for the TR2 brakes. If it has a decent TR2 motor with good chrome liners and proper gearbox etc then thats a different story. I sold one a few years ago for $7500 , but it was a little nicer, mostly original and had matching numbers. It was a bargain and the fellow was happy to have it. It would have brought way more than that in Europe. If you really want to know what it's worth, figure out exactly what you have and put it on Ebay with lots of info and pictures. Be willing to crate it and ship it to wherever. I'm just kidding... but it would help if you can dig up documentation stating that it used to belong to Yvon. He raced one back in the day.
