    Thanks guys for all of the replies. I'm looking at one locally that has 14,000 miles and is in decent running shape for about $600. I'm buying this as a beginner's motorcylce.

    Cheers,
    Victor

    P.S. I personally wanted the SR500, but some of the things I've read indicate that a more experienced rider should own that bike.

    a friend had a 77( ?) xs500, a steaming pile of shit. ( in fact it was brown, who makes a brown motorcycle unless they really knew it was a steaming pile of shit?) I dont think they share the same engine. lucky for you.

    buy some good gear and take a MC riders course. check over the brakes, replace the fluid, some of those early disc calipers freeze up. do a through test, as old bikes the rubber dries up, carbs can be a problem. dont let that stop you.

    My gf was astonished when I spent $600 on an Arai helmet just to ride my Honda Ruckus scooter. I've just recently acquired a Yamaha Riva 125 and the XS400 would be the next step up. Full face helmet for me all the way at any speed. Also have a Joe Rocket mesh jacket, but that will soon be replaced by a leather Vanson I've had my eye on for some time.

    Once I transport the Yamaha back home in a pickup truck I'm taking it straight to the local private bike shop to be thoroughly checked out.

    The MSF course is a Xmas present I'll be using before the bike.

    So when can we expect the questions about a 14 tooth countershaft sprocket as opposed to a 16.

    Or where to get a set of 17" wheels so you can motard it?

    Different weight springs front and rear cause you're obese, like most of the rest of us.

    Which 6.9 gallon gas tank is best.


    And the two ALL TIME FAVS; what kind of oil and tires does everyone use.:evil:evil:evil

    I forgot; flat or dished Corbin, that's always a good one.

    Have fun with you new toy, but until you get a dualsport....

    Hehe, I'll let you all know how it goes. When I have more experience under my belt, and more cash, I would be gunning for F 650 GS.

    My friend has the XS400J, which has somewhat higher performance specs.
    Fun little bike to ride...

    Vertical Twin, Had one. Not a awesopme but great little bike. Reliable, fast for an old pokey air cooled 400 twin, and easy to maintian. Looked OK for a chopper wannabe Japanise bike. handled well enough for the Snipe to put allotta guys to shame...amd shame it was to be passed in a corner by a Yamaha 400 Special.

    Actually even though the SR500 is a sweeter bike, a 400 special will beat in in a drag race.

    When I was a lad XS's were considered a bit 'girly'. Real men rode RD's but we were only allowed the 'two fiddy' as learners in those days and they were fast enough!.......:D

    Seriously though, the XS400 will make an excellent bike to learn on and congratulations on making some smart choices. Like the old Bell Ad said, 'if you have a $5 head, wear a $5 helmet'.

    Regards

    Not a speck of truth to that, although you'll pay more than $600 for a decent one. The XT500 dual-sport is also a good one, and shares the engine with the SR.

    The ONLY challenge to an SR or XT is they are kick-start only. Have it tuned right (not rocket science) and learn the drill. First kick every time if it's running right. The compression release makes it pretty easy.

    The XS400 is a great little bike and would be a fine starter, but an SR is way more fun IMO. It's also one you'll hang onto forever, unless you're an idiot like me.

    Nobody drag races either an XT400 or an SR500. Don't use that as your benchmark. Either one will take you where you want to go at above-legal speeds.
