While the seat on the 1K Raptor is fine, especially with new suspension beneath it, that on the 650 is hard and appreciably narrower at the section where I feel comfortable with the riding position. Now, however, Alistair Else at ElseMade in Wisbech has reworked it with gel and memory foam, making it appreciably wider at that point. It now feels superb; rather better than the 1K, in fact.
Cosmetically, Alistair has replicated the original look as requested so the appearance is little changed: it just doesn't look anorexic anymore.
Maybe tomorrow the roads will be dry, if not actually clean, and I can have a comfy ride!
