    Hi there, just got my 640 last week with 5500 miles on her. PO put on Akrapovic pipe and a rear Touratech rack. I have added the compulsory headlight guards and the Nuvi Touratech GPS mount. Other than that seems stock. Couple of questions....

    The vibration ..... I came "up" from an 08 KLR 650 and am amazed at how buzzy this thing is. I think my hands will give up far before I run out of gas. Any advice on reducing any of this?

    Been researching skid/bash plates with the intention of buying one with tool carrying capabilities, only to find the aftermarket segment for this bike seems to have shifted to the 690 Enduro. In searching here, is seems that KTMatt out of Aus makes them and I have sent him an email (without reply yet, but its only been a few days). Any other options?

    Any advice appreciated

    Cheers

    Vibes?

    We don't call them Vibes.

    We call it Nervous Energy.

    Seriously, you do get used to them and they tend to bother you as you drone down the hardtop. Offroad, you'll never notice them.

    Changing the gearing makes a difference. On my '03, and the '07 you have to find the smooth in the rev range usually around 5k rpm and gear for 70 to 75 on the interstate. I toggled back and forth between a 15/42 and 17/42. I'll drop it down to 15/42 if I know I'll be on some more technical riding but real buzzy on the interstate. Stock is 16/42 FWIW.

    Alternating two teeth in the front allows you to flip the rear axle block without having to fiddle with the chain tensioners at all.

    Well thanks. My typical riding is 300 or so miles of slab to get to 300 of dirt. I can give up a little on the dirt for an easier tarmac ride.:1drink

    They're spendy, but a kako (however you spell it) throttle lock is money well spent which will allow you to shake out that throttle arm to get the tingles out of your fingers here and there.

    I bought the '03 640A after I had spent two years reading up on them. I had never even ridden one of these bikes and had never even seen a 640A in real life before I bought the bike. They're huge. I was expecting the vibes I kept hearing about, but I didn't expect the bike to walk across the shop floor while it idled on the center stand. Holy F###@@@K were the two words than I kept muttering on the 20 minute ride home from the shipping company. I was seriously worried about the vibes, dealing with the vibes, the numb fingers.

    It's a freaking mean vibrating beast, the 640A is, but that's why we love them.

    You're gonna grin your fool head off every time you ride that bike of yours. You'll get used to it, it'll get used to you.

    Huge? I actually wish it were a little more roomy but then again I was raised on big framed husky's, Cam Am's and KTMs of the 80's. I'd like to find a taller saddle some day but the Rencazzo the previous owner put on it is like a sofa.

    I had to drop my truck off once for undercoating, I unloaded the 640 to ride to work, set it on the center stand to let it warm up and got my riding gear on. I turned to get on it and to my shock, it was gone! I kept turning and saw it had vibrated down the parking lot and the rear tire was hanging into the street.

    My friend, the previous owner, rode it 4000 miles to Alaska and back for the Alcan 5000. Said he'd do 500 miles or more a day and lay in the motel at night still vibrating!

    Personally the vibes don't bother me, I can ride the beast all day long.

    Big for me. I'm 5'8" and not a big guy. On the center stand, the seat on these bikes almost comes up to my elbow. I'm coming off an XR-75, loads of real metal 60's - 80's Vespas, and a YZ 450.

    I tried an inexpensive thumb lock style (forget the brand) first. The vibes in the bars were too much for it, never held more than a few seconds. The kako works!

    Hi everyone, I'm a new KTM owner after years of drooling and dreaming. Back in '03, I checked the 640 out at the dealership and fell in love. After almost 10 years, I just picked up my 2003 640 Adventure. Drove 1800km's and 20 hours to get it, and it was worth it. I took it for a burn today and it's better than I imagined. She's bone stock but that just means I have a clean slate....time to accessorize!

    Welcome to the club, Legs.

    You have come to the right place for advice on these bikes.

    Bill, were the weights on when you bought it? Mine were but kept snagging trees in the woods so they are dampening the shelf now

    You know I also have a Buell X1. The KTM skips along the driveway at idle. The Buell moves the driveway. :lol3

    I put them on back in the day for traveling. I'm not riding single track...I blew my knees, hell my legs, out long ago riding enduros and mx in the '80's so I stick to the ATV trails now.

    If I was woods riding on single tracks I would cut the bars, ditch the bar ends, gear down, run knobs, yada yada.

    :rofl I wish I could get the grunt of the Buell I rode in the motor of my 950. That thing made all it's power between 400 and 4000 rpm it seemed. I guess if it revved higher, it'd vibrate itself to death? Sometimes it feels like my 640 has more low end than my 950

    Yeah the Buell is very quirky. Vibrates like a bastard until 2500 rpm then you are on a cloud (comparatively speaking of course). But for all that torque is does have quite a narrow power band. The old tube frame models (x1s) are the bargain of the decade right now. Never got to ride a 950/990. Was offered at an ADV event, but I was on my KLR at the time, and just knew I would be crying in my helmet all the way home if I did. :rofl
