Hi Sprintster,
I have some knowledge about T300 bits. I cannot help with the T500 queries though.
My '96 Sprint came with the "Sport" bars - apparently it was pot luck which bars were fitted by Triumph at that time, according to my dealer. They are great for summer blasts/rides.
For the winter trim I got hold of a pair of Sprint "standard"/Trident bars (and a higher screen). I did not have to alter clutch/brake lines or choke/throttle cables - so the change is a 15 minute job.
I also have (in a box somewhere) a pair of UK spec Speed Triple bars - they are clip-on type (unlike the US model with its different yoke and handlebar risers) and I think you can see these just in the Photo Albums section
UK Speed Triple . I have this idea about trying my Sprint naked sometime - I believe the fairing would be a problem for these bars though.
If you do go for the "Sport" bars, make sure you get the bar-ends/weights as well. I have all the part numbers somewhere, but far cheaper if you can pick them up from Ebay. If you would like more information, send me a PM - it may take a little time to dig the things out, but I should be able to help.
The other thing that you may be interested in, to help your riding position/style, are the positions of the footrests across the T300 range. By changing the brake push-rod and gear linkage (e.g. Daytona/Speed Triple), you can move the footrests to the other mounting holes on the 'control plates'.
Hope this helps? Sorry, no knowledge about the T500s.
Ciao, Geoff
