could it be a 21" front wheel that is making it appear the front end is tucked?

Pretty sure that's a 19" wheel there.
The more I look at it, the more I am sure the tire will hit the front cover if you pump the forks hard. Hope not!

Maybe one of you will be kind enough to measure a swb R75/5 from the front axle to the points cover so I can take a look. It certainly has been cobbled together from a wreck as it does have a salvage titled frame. The only bent bits I could find were in the subframe, now replaced; that said it's the only R75 around so there's no "good" machine for me to compare. Don't let the tight angles in the little shop fool you, the forks are okay; not perfect but okay.

No worries Supershaft, after 40 years of riding I'm not much of a rider either...

ok I may be wrong, SS may be right.

I measured 7 inches from my tire outer diameter to the nearest point on the front cover.
This is a close estimate as I didn't want to remove the fender to measure directly from the tire.
I'm also reluctant at this time to remove the wheel to measure from the axle, though that's not difficult.

Oldroadie, you may enjoy this bit of reading: http://www.tonyfoale.com/Articles/RakeEx/RakeEx.htm
when I first saw the pic of your bike I was reminded of photos from Foale's tests, but chose to assume the best.

I don't know whether it's been mentioned particularly in this case, but your frame/headstock gussets need to be virtually flat, no deviation allowed beyond minimal distortion adjacent to the welds... i.e. due to welding.

here's a pic I took this morning

The problem is I always choose to ride over modify, its "continually under development and evolution" Tires are next Maybe K70's, sizes are hard to find with that 3.25 front. Maybe you have some recommendations.

I wish I had some good recommendations, not a lot of 19" dual sport options as I'm sure you know.
I'm currently running a K70 on the R80ST and have no complaints but it is a street tire, only looking a little aggressive (in comparison to other streets).

this old thread may help:

I have been reading good things about Heidenau K60's from what I read they stick really good, last long (about 7k miles), and are cheaper than most. ($120.00 for 19" front on ebay) here is a link http://basinmotorcycleworks.com/heidenau.htm

I am leaning towards putting them on my ST before spring

I have them on my r90...if that helps.
They're a dream! Kind of scary in the rain, though.

Your best bet is to look for bowing in the gussets underneath the steering head. I think I can see it in the photos but that is stretching it even further. It might be just the lens.

I hear ya! 44 years now non stop for me except for injuries like right now.

Not to add more anxiety to the frame issues, but it looks in the rear shot, that the rear wheel is leaning ever so slightly to the left relative to the bike itself. Again, could be distortion.

What size rear do you run, I need a 120/90 18 for my ST and can't seem to find one in stock.
