Craigore - yup, Lowbrow grips. I really like 'em! I wasn't 100% when I saw them online but now they're on the bike they are perfect for me.
2wheelsdown - the satin chrome effect is easy. Green scotchbrite pads.
Fender - I didn't realise when I bought the mirrors that they were copies of Rizomas. Generally I'm not a huge fan of copies. But these are not cheap and nasty copies, they are well-made copies! They're about half the price of the Rizoma mirrors, are extremely well made and were easy to fit. The adaptors come with the mirrors and you just need to get the right length bolt and they screw straight to the bars, being genuine Triumph bars. The fit is rock solid and they work well. I get the best rear view of any mirrors so far with these.
I'm very happy with how it's coming along. The side covers make a huge difference to the look of the bike. You can't really tell from the pic but they're kinda dome shaped which looks very cool and I think the finish came up well.
Once I get the shorter fenders on I'll take a few more pics of the whole bike. BTW I stole the idea for the taillight from kdlutes here. I got the light from Lowbrow.
Thanks for all the positive comments guys! It's nice to know I'm not 100% crazy. This bike has been a revelation to me. Most fun bike I've had.
