640 Adventure question

I want to enter the world of KTM and am looking at a used '01 640 Adv. My one and only question is how comfortable is the bike when doing a long day or multi-day ride mostly on pavement? I know the gel seat adds some more cushiness to the butt, but does the bike vibrate tons etc. Thanks!

You may want to look for a '03 as they were much improved as far as vibs go. The bike is a great all arounder. Check at ktmtalk and advrider for tons of great info on these bikes.

A big single will vibrate a good bit. Rejetting the carb will help a lot. I guess it is a personal thing on vibration.

There are a few things on the pre 03 models that you should be aware of. One is the bearing replacement. Check out advrider and ktmtalk for lots of details.

Many folk love the adventure for long trips.


I sold my 2002 LC4 Adv. after logging 13000 miles on it. Longest stretch I've done on a single day is 700 miles, but about 4-500 miles I was ready to get off. Padded bicycle short works better then gel seat. You can even wear two pairs of bicycle shorts if you really want to be comfy.

In the beginning the bike would "walk" down the driveway by itself when idling, because of the vibe, but eventually that stops.

For long trips on pavement/highway, you really need to have street tread tires to minimize the vibration.

The LC4 engine vibe smoothes out alot after 6-8000 miles, good valve adjustment and also going to Mobil 1 redcap made it smoother, too.

Thanks for all the tips!

      What are these? Big heavy 550- 600 pound road bikes with dirt tires and an upright position?
      That seems to be them.
      To me an "adventure bike" is one that you travel on remote roads which aren't developed.
      If you're not able to pick it up when you drop it ( and you should daily ), then it's not an adventure.
      Try picking up a 600-700 pound bike by yourself on a loose steep road....ain't gonna happen.
      So it beats me why these bike manufacturers don't take a DR,KLR,XR and give them a 6 speed tranny, and a modern suspension. These are the real adventure bikes...fun,light and you can power slide and get her loose without worrying about being crushed when you drop. The only one that's up to speed is the KTM. Instead, these are stuck in the 1980's tech department.

      Hello all,
      Long time lurker, new member here. Read the LC4 thread index on adv but couldn't find any help there.
      I own an 04' 625 smc with about 15500 miles.
      It recently went out on me. The rocker arm follower bearing seized and cause havok inside the rocker cover. New rocker arm assemblies (intake and exhaust) installed, new rocker shafts, new 690 rallye cam, and new cam bearings. The old cam was shredded from the follower bearing seize.
      So now that's all replaced and put back together, there is another issue. Though it may be the original issue that caused the follower bearing failure in the first place.
      My oil flow into the frame neck seems to be very low to nill. I can not get the frame to burp oil out of the upper frame plug as needed. It ran for 5 minutes without any oil coming out. There seems to be little to no oil building up in the frame tube. Either its being suctioned out too fast or pumped in too slowly. 
      So question is, what to do? I have checked the oil lines going to the frame neck for debris.
      How can I properly check the oil flow into the frame neck?
      I've read that the oil bypass piston on the bottom of the sump can get stuck. 
      Although this doesn't seem like it would cause the low oil flow.
      Could it be one or both of the oil pumps? If so, how can I check the flow/pressure these are putting out, do I just loosen all of the banjo bolts slowly to see if oil is flowing?
      Any help would be greatly appreciated,
      Thank you,
