If that is your bike and it is stock you need a 126mm spaced wheel for a 6 spd uniglide or "twist tooth" freewheel not cassette. if you can find one I think a 6spd Uniglide cassette wheel will fit and be interchangable but those cassettes are getting hard to find.

If you need one, I have a 6 speed Shimano 600 13-23 freewheel.

Harris Cyclery has IRD freewheels in the same 13-24T gearing, and Shimano 14-28T freewheels that I'd favor.

The catalog page lists "Freewheel." My '88 ST400 also was equipped with a six speed freewheel, so I believe it is safe to assume you do not have a 6 speed UniGlide cassette installed currently.

Therefore you should be good to use any regularly spaced six speed freewheel, just make certain you stay clear of Suntour Ultra Spaced six speed freewheels. They will be too narrowly spaced for Shimano SIS indexed shifting.

Really, it depends if you've got an HB-1050 or HB-1055 hub. The former users a freewheel, the latter a cassette. They're both Uniglide, but I'm suspecting you've got the latter given the specification of SIS shifting and assuming it's the original wheelset. I'm keeping a Shimano 600 uniglide hub working, but yeah the cassettes and even individual gears are getting pricey on the market. Seems there's a few in stock in the UK, but with limited selection at SJS.

If you mouse over the blue text in some of our posts, you'll see links to info and current production freewheels. I think Justin's would be the most authentic replacement.
