Don't know, but it does need some TLC (tender loving care)
I have replaced a lot of bits since I bought it, but what would you expect with a 26-year old bike? - Brake pads, fork seals, chain and sprockets, exhausts (Mufflers), float valves (both) and numerous minor fittings.
I've had to re-coil a number of threads that had been stripped by previous owners and glued up (probably the same owner) including one of the main rear engine mounting bolts.
The fully enclosed drive chain is a good idea; supposed to give 50K+ chain life, although it is a pain to change chain and sprockets.
Very comfortable to ride, even at slow speed around town and through traffic, but the steering feels a bit heavy as it really wants to fall into corners, and significant counter-pressure needs to be applied to maintain a constant radius corner. The narrow handle bars are a real bonus when moving between stationary traffic.
You mentioned it 'falls' into corners - that was why I could out ride most other people through twisty roads on my XV1000 - it turns into corners very well, and with its bottom end torque pulls out of them quicker than a top-endy 4. Those old XV1000s handle like a dream.
Fortunately it doesn't handle like a Honda Dream... I've just bought my third XV100 (TR1) in as many decades. It could well be the best all-rounder ever to come out of Japan - as long as you don't want your all-rounder to come with no pillion accommodation worth talking about, or to be covered with plastic, or cursed with a head down, bum up riding position, like most 'all-rounders' seem to be nowadays. No, the XV1000 (TR1)'s a proper motorcycle with a characterful motor, plenty of comfort and if you have the later, restyled version, it's even good to look at.
