Bagging up

Today I have spent a few hours in the garage looking at where to mount a Kriega US-5 to carry my tool-kit or my medical pack. First I was looking at the rear fender.

Took a while to disassemble the rear of the bike, only to find out there is no space for the bolts. Looking at the above picture, two most left holes, didn’t have enough space below the fender for washer and a nut. So I reluctantly reassembled the back end together. Checking out the bike with a stuffed bag, I have found a nice spot, on the fairing just above the headlight. On a second thought, that fairing might not be strong enough to support the weight of my tool-kit over rough terrain.

So the only spot on the bike left, was the tank. The stuffed bag looked good on the tank, but I don’t have Kriega tank adapter, so I needed to figure something else out. Bottom strap was not a problem, just threaded it under the seat. Top was a bit more challenging. Straps wouldn’t fit around the frame tube, so I threaded them around radiator shrouds. I was quite happy with the position of the bag, but didn’t like all the straps hanging around. After a few more attempts, I was happy with the result.

There is enough room at the handlebars not to interfere with steering, or steering lock.

It sits nicely on the tank. And it won’t get in the way when standing like a standard tank bag.

That is it for now, field test will be done as soon as the weather improves.

Stay safe!


The stock tank on a 640 Enduro only holds 12l, that is enough for around 180km (depending on how you ride). The size of the tank is great if you are riding around in bush or local fire roads and trail, but if you want to do some more adventure riding you need a bit more of a range. For this matter I have decided to get a 18l KTM OEM tank for the 640 Enduro/SM. Those tanks are really rare here in Europe, so I looked over to the great USA for it. They have a lot of good stuff over there for the 640’s., including the tank I need. The prices for those tanks are really cheap, when you convert them to €, but unfortunately shipping and import charges are usually a deal killers.

Scouring the European e-bay system I have found a good tank, and lost the bidding war. By this time I have already been mentally preparing myself to cash out for a brand new tank form KTM. After patiently looking around e-bay for over a month, my luck has changed. There was a tank posted with “Buy-it-now” option. I have quickly contacted the seller about the shipping price and negotiated a bit lower price on the tank. After just 4 days, the DHL showed up with a huge box for me.

Inside was a well protected tank.

It has a grey decal already on so it fits my bike perfectly. Also it came with a fuel tap and a few scratches.

First thing I did was weight the tank, as it felt really heavy when I took it out of the box. It weighs 5,8kg which is just under 13 pounds. Next on the list was filling the tank with water and check for any leaks. Luckily no leaks, after a quick flush I drained the water.

Now it was time to see if it fits on the bike as the OEM part number said it only fits 2000-2002 KTM 640’s. So I began stripping the bike down.

Before taking the tank off the bike, I have drained it off fuel. I didn’t want to handle the tank with gas in it like I did on KLE usually.

To remove the tank you also have to remove the the side covers. Underbelly wasn’t cleaned for a while I guess.

Naked bike.

Before putting the big tank on the bike, I took some measurements of both tanks to see how much wider is the 18L one.

Stock 12L tank with shrouds it’s 43cm or 17 inches wide and the 18L one is 49cm or just over 19 inches wide. That is 3cm or 1,18 inches wider per side. So overall the bike is still very slim, though it looks a lot beefier with this tank on. There is a bit of a gap between the seat and the frame as I haven’t bolted anything down, just assembled it together.

All in all, the 18L tank with part number 58407013200 fits a 2003 640 Enduro perfectly, though it says in the part numbers that it wont. That is maybe because KTM has released a updated version of the tank 58407013400, what are the differences I do not know only that 58407013200 tank isn’t available from KTM any longer.

So that is one thing sorted out, next big thing on the list is a luggage system and a fairing of some sort.

Stay safe!

I have bolted everything down and it looks like the gap between the frame and seat is there to stay. I guess the really is a special “18L seat” to go with those tanks.

For city commuting, a day ride or a long ride a motorcycle tank bag can be a really handy little piece of kit. A tank bag can store enough essential gear to get you where you’re going and back, carrying just the items you need to get around or need to have in a reach without having to get off the bike. There are different tank bags on the market, from small to big ones. They also differ in shape(flat for street and curved for enduro bikes) and in the way they mount from magnetic to strap to special attachments like to a tank ring or a tank cover.

I have been searching for a tank bag for a KLE the whole season. Surfing the internet didn’t produce any reasonable options that would state that it fits or was made for KLE. There was a SW-Motech tank ring tankg bag but at price 120€ for bag and another 25-30€ for a tank ring. So after looking for a new one, and getting nowhere, I started searching our local sites with used motorcycle gear. My theory is if you are not sure if something will fit your motorcycle, buy it cheap or used and save the rest of the money in case the bought item doesn’t fit and you can’t return it.

One day I got lucky, a man was selling his SW-Motech Enduro strap on tank bag that he had on his BMW F650GS. Since GS and KLE have similar tank shapes, I called him and arranged a meeting to see if it will fit my KLE. We meet the next day, checked the bag if it fits and closed the deal.

Here are a few pics when I got home:

Side view



The bag has 3 outside pockets (one at the back side of the bag and one on each side of the bag). It also has a transparent map pocket and a nonslip base which can detach the bag with a zipper.

Main compartment is big and red

Fitting the bag on the bike:

The bag comes with 2 different mounting options, a plastic hook for round frame bars and a loop strap.

I chose the loop strap fitting as the hook is too small to go around the frame tube, but it fits SW-Motech’s crash bars perfectly.

I took the side covers off the bike and looped the strap around the main frame bar, just below the sub frame tube. On the right side there is plenty of room for the strap, but on the left side you have to take a bit more care because of the cables that are there.

After this just reinstall the side covers. Side covers have a curve right at the spot where the strap comes out from underneath, looks like it was made for for it.

With this done, we move to the front. In the front there is only one strap that should go around the head tube. But I don’t like warping anything around there that could interfere with steering. So I warped it around the top main frame tubes.

Here the strap is not tightened yet, when tightened the strap in the middle goes under the tank.

Leftover strap just tucks under the bag

This is all that is needed to mount it up.

The cockpit view is unobstructed

I forgot to mention before that the bag is also expandable

Even when extended the cockpit stays in full view

After a short test ride I was surprised at how unnoticeable the bag is. It doesn’t move around at all and full turning radius is possible. The only time the bag got a little in the way was when standing on the pegs going in a steep hill off road and when refueling you have to unclip the back straps and turn the bars on one side to clear the gas cap.

Safe riding everyone!
