On the S1000R forum I've been asked about discounts, so to keep everything equal I'll repeat my answer here....
People who've been following me on the Triumph Tiger forums will know that I've dropped the price of the books from £25 to £18 across the board, so I can't offer a further discount on those, but I can offer a 10% saving on the first five pairs of light brackets sold through the S1000R and S1000XR forums.
I'm also happy to discuss group buys, for more than 10 of any one item.
