1992 K75 leans way too far on side (kick) stand.

The seat height is 810mm, lower than an R1200GS unless the GS has lowered suspension, maybe. If "standard bike" means roadsters and retros as offered by Yamaha, Honda and Kawasaki, it's taller for sure. It towers over most HDs. But many folks express the seat height is inconvenient sometimes. Maybe that's why it leans more than the others; that makes mounting easier if you're not using a footpeg to help.

I have a 1250GS and a 1250RT.  The k75 seat height is between the 2.
I like higher seats.  More comfortable for
My knees.

Is that a Givi top case platform on the cowl? If it is, how long has it been mounted on there?

[mrt6644]

No it’s a SW Motech tail bag.  Mounted with straps

[Laitch]

I'm referring to the tail plate circled in this photo.

[mrt6644]

Oh, I thought that was stock.  I’ll take a closer look

[mrt6644]

I don’t see any names on the rack. I’ve always thought this was a stock top case rack.

[Laitch]

This will explain it to you.
This is one model of several cases Givi makes for it. It's good for clothes but don't put heavy stuff in it. It can crack the tail cowl. How you're using it is good enough.

[mrt6644]

I don’t really use the rack at all.  The tail bag sits on the passenger seat.  I haven’t really haven’t used it for much although I thought of bolting a Pelican case to it.  But not sure the weight capacity.

What model is that case?  Maybe that’s a better option than a Pelican case.

[Laitch]

It's a Dolomiti 30 liter.

[mrt6644]

Seems pricey.  I’d probably lay just bolt one of my Pelican cases

[Laitch]

That's a more reasonably priced option, especially if it's free.

[mrt6644]

yeah, I have many cases I could use.  But, they're not light.
