My advice is try it bud if you can!! Reason being, I (unknowingly) had an '02 seat on my '00 model which worked!! It didn't fit as snugly as the correct one would've but it was secure nonetheless bud..............:thumbup
Cheers guys,
Can't try it unfortunately as it's off fleabay and not going to take the risk. There is another for the 02 but was gonna try the other as it's a little cheaper but I'll have to dig a little deeper:angry
I think the academic answer is, they will both fit the other bikes i.e. a 98-00 seat will fit a later bike and vice-versa, as the seat lock and mount points on the subframe (if it has a 2-person subframe :dowhat), and where it "slots" under the rear fairing, are all in the same place.
I know this because my old Mille (99) came with a seat which fitted, but for love nor money, I couldn't work out why the renntec grabrail wouldn't fit with it :angry Turns out that I had the later seat, and as someone else has pointed out, the profile of the earlier seat is much more pointed, whereas the later one has a large ridge down the centre of it, and is much wider at the back (hence why it wouldn't fit with the narrower profiled renntec, designed for a narrower seat)!
