On a side note, It's nothing personal but, it's not really a torsion bar... Torsion/torque implies it's being twisted which it's not. It's being stretched so it's more of a stay bar. A common mistake but a mistake none the less

It's nothing personal , but it restrains the torque imposed on on the caliper carrier when the brake is applied. i.e. trying to twist the caliper and carrier round the wheel spindle.
Strange that in a parts list I have it is called a compression bar!
To get back to the main topic, the bar is 240mm between hole centres. I have an alluminium one on my bike that is the same length but not sure which Yamaha model it came from.
Hmm, I see the point you're making but the bar itself is still not being twisted... Guess it just depends how you look at it.
Yes, back on topic. I removed mine, sanded it and sprayed it black during my winter fiddling last year and it looked good as new. Took about 20 minutes + time for paint to dry but looked much smarter again. I also painted the caliper carrier black too, much neater than the grey/silver it was.
