Seems reasonable if it runs well - especially if it's been running recently and you're not looking at a complete rehab.
You can reupholster the seat and get new tires for less than $200.
Hondas are cheap in these parts, but those 750s are getting harder to find. It's a cool looking 'ol bike, looks like everything is there.
Around here, $1200 USD would be a steal; $1500 a great price if it runs well - $1800 would be fair - $2000 would be reasonable, but starting to edge toward a premium price.
