Looking to finally put some rearsets on the ol' 990. Seems my choices are limited nowadays and looking at the few companies that still make them, I only find that the ones made by KTM (part number 61103038044) allow adjustment down.

Is that so? Any others that I should be aware of?

Thanks
Troy

If you enquire with a dealer about the KTM rearsets you could find that they've been discontinued - that's what I found when I tried ordering the race pattern gearshift kit
My 990 track bike has Sato Racing rearsets fitted - they came with the bike so I can't comment on the cost or ease of fitment but they seem to be well mage and have plenty of adjustment available. It's possible that Gilles might do some, but you may struggle to find any for an obsolete model that was never a big seller - if you were looking for them to fit a `99 R6 you'd have loads of options, but the scarcity of readily-available aftermarket parts is a price we pay for exclusivity I'm afraid
