XS wheels on an XJ seca

[Ltdave]

dont you just hate noobs coming in and starting right off with a question?

i dont care for it none too much so let me introduce myself first...

david here in the thumb of michigan...

have owned an 81 yamaha maxim 550 since 1992. rode it while in the Air Force until 1994. got it back out of the back of the garage last summer and been cleaning and polishing...

just bought an 82 yamaha seca 750 last month...

they both run pretty good and im in the midst of tweaking them for top performance...

heres the question: will the wheels from an XS 750 or 1100 fit an XJ 750? they are all shafties so that shouldnt be an issue. the seca currently wears a 120 tire out back...

thanks

Hi Dave,

If the 750 Seca you got over there is the same as the UK model, then the XS wheels won't fit straight on.

The Seca has a 15mm front spindle, the XS is 17mm, plus the XS hub is a touch wider through the bearings.

The splined hub to drive the wheel from the rear bevel is not the same on the two bikes; the seal and spline are the opposite way round, so the XS wheel does not fit straight onto the Seca hub.

The XS bevel is longer (between the flange which bolts to the swing-arm and the spindle-hole) than the Seca, the shock mount is in a slightly different position, and the drive-shaft has a different arrangement on the two bikes.........so the bevel does not easily swap over.

ALL of these things can be overcome....... If you have the time or facilities........ I have done most of 'em! but none of the swaps is easy.

Recommended tyres for the XS11 is only a 130 x 16/17, so you would not gain a huge amount anyway. The later Euro XJ900 uses a 150/17 on a 4.00x17 rim, which would be a lot easier to fit to your Seca (similar drives...I think!). I have one of those on my XS.

All of this may be nonsense if the US model Seca is different to ours LOL.... some of my XS11s are US models- so I know a little about those.

wow. thanks for going thru all that...

i mostly just wanted to change the wheels. i wasnt too concerned with the width tire i could stick under there. too bad the seca wheels look ridiculous..


thanks again for your descriptions

Hi Dave,

It tok a lot of pain to figure all of that out; It is good to be able to pass it on!

Used to own a 750 Seca. An absolutely great bike in all respects except for the almost rigid rear shocks...easily remedied though.

Hi LT,
I too prefer the "artillery wheel" style of the XS series cast wheels, although there are sound technical reasons for casting wheels with "swirly" spokes. However, those reasons only apply to sand casting in iron, not to pressure die-casting in aluminum, so we are back to one's preferred aesthetic. Alas, as has been posted, swapping XS wheels into your Seca just ain't gonna happen without you pour a massive amount of expense and effort into the project. Look at it this way, you can't see the wheels when you are riding, right? Just don't look at the bike when it's parked.

You might have better luck with Virago rims, same rear differential and gear ratio. Some Viragos had wire wheels too, if that's your style.

Fred sometimes you crack me up. Or maybe it is you widen the crack :}
