The blast is tiny.

the blast is low as hell, something like 25 inch seat height. so if all else fails that will work. I think at 5'4" the 250 is the best option. has she sat on one yet? even if its only balls of the feet she should still be fine. its light as hell too. if she hasnt sat on one then i wouldnt write off the 250 just yet because seat height isnt the only stat that matters... if the seat is pretty slim its easier to handle generally.

Must've been a Bolt then.

Most likely. Have her go sit on a bunch of them. I can't flat foot by bike without my balls against my ribs, but still feel comfortable sitting on it.

I'm for the lowering and then raise it back up later. As long as you lower both the front and rear the geometry won't change. Mine is still slightly lowered.

The 1125 is high too. I'm 5'9" with a 34" inseam and can just barely flat foot it.

When I was reading the specs online, the seat heights were comparable to the big for liter bikes, but then I realized that Jap bikes are measured by themselves. For some reason Buell measured seat height with rider on board, so the suspension was slightly compressed... wierd.

The XB's are relatively high up... The Ulysses (XB12X) are fuckin' ridiculous, with like a 35" seat height or something...

I am 5'11" with a 32/33" inseam and couldn't flatfoot my Buell... even with my fatass compressing the suspension...

I think the Blast has one of the lowest seat heights of any sport type bike...

Yeah, my R6 is 33". The Buell just felt so high up. Good for ground clearance though.

Or underslung exhaust...

Actually, yours is higher than the Ulysses!

Highest of any in the sportbike class.
