Street Twin Seats on Street Cup

I've only found threads where people have been able to fit the Street Cup seat on their Street Twin, and this without anything extra being done and without issue. It would seem logical then, that a Street Twin seat would fit on a Street Cup without anything extra being done and without issue, but could there be some strange difference that makes this not the case? Has anyone put a Street Twin seat of some sort, including the Bench Seat, on their Street Cup?

I have no experience of the actual conversion you mention, dude, but I'm pretty sure it will fit straight on. There's huge interchangeability of parts between the various models in the 900cc range. They're, essentially, all the same underneath. Maybe someone will let you try one?

I can tell you this: I was in the dealership last week I and tried to put a Cup seat on my street twin, but we could not get it to fit on properly. There is a bracket underneath the street cup seat that was non existent on the street twin seat, so we took the bracket off thinking that it would resolve the issue. It did not. Now if I had had more time to screw around with that I’m fairly confident that I could have gotten it to fit, but I didn’t want them to think I was going to break the seat. I went ahead and ordered a Streat Cup seat anyway, which should hopefully be here by the end of the week.

Guess we’ll see what happens.

Yup it'll swap right over. Seen it done before. Check the "Triumph Street Twin | Cup | Scrambler" Facebook group and people can post pictures.

I put the cup seat on my twin with no modifications.

I put the stock Street Twin seat on my Street Cup, no fit up problems at all. I have the Triumph rear rack/grab rail installed also. To make the stock Cup seat work with the rack you have to remove the 2 rearmost rubber bumpers on the back of the seat. The Twin seat works without modification whether the rack is on or off.

Thanks for all the info everyone. Sounds like it's no issue. That's great to hear.

That's interesting. As for hard luggage options. So far I've only seen Hepco and Becker, but they only list for the Street Twin, and not the Street Cup. I'm wondering if with the Street Twin seat on the Cup, those racks would work?

Yea, I think I could have put it on with a bit of jiggering but when it didnít snap right on the sales guy got jittery. He had parts take the metal bracket off the bottom and it still didnít snap right in.

Like I said, I still ordered it. Should be here in the next couple days. Not worried.

I got a ST seat for 2 up riding and strapping a bag on for a day trip. At the dealer noticed basically two kinds of seat pans, deep and shallow, the shallow worked. Just grease up latch, turn key push seat forward and up to fully disengage latch.
