What are the differences between European and Japanese hardware ?

For instance—will Honda/Kaw/Yam M6/M8 bolts work the same on a Ktm/Husky?

a m6 bolt is a m6 bolt. if its the same thread pitch and length it doesn't matter what manufacturer its from

Just make sure your tensile ratings are the same 👍

I think the biggest difference is what might be a 12 or 14mm wrench size on a Japanese bike will be a 13mm on an Austrian bike. I never used a 13mm wrench until my grandkids started riding KTM's. Got used to only carrying an 8, 10, 12, 14, 17 T-handles to the track, not anymore.

Another thing which really isnt a huge deal but might be worth mentioning is that the ktm bolts have torx in the inside which saves a tiny amount of weight over 100 bolts and also if you ever strip a bolt somehow you can use the torx in the inside to still remove it. They also have a more modern better look imo.

Another nice thing about KTM .If you lose any plastic fasteners you can go to home Depot and pick up some drywall screws as replacements 😂😂

14mm to 13mm is weight savings!

My argument wasn't about weight, it was about the fact I now had to carry around more wrenches.

Another cool thing is that KTM/Husqvarna/Gas Gas bolts and fasterners seem to be coated with something that actually lasts some time. And torx beats the living shit out of hex heads.

Really I actually think they start to rust pretty easily compared to the nickel coated stuff on the Japanese bikes. If I could get these KTM bolts nickel plated or better yet cerakoted ( likely never happen cause of cost) that would be ideal cause I prefer the looks of the ktm bolts but as soon as you put a wrench on them they begin to rust imo.

My local plating shop does a full 5 gallon bucket of bolts zinc for like $150 or at least they used to 2 years ago might be more now. Color does change the cost a bit. They also do rack plating where they wire up each bolt individually but it costs a bit more.

Not really. You substitute the the 12 for the 13.

I was thinking of buying a diy plating kit or cerakoting myself but bought a full kit for 60 bucks with all new hardware. Literally has every bolt and even spares except for the suspension, engine and main chassis bolts. I actually ended up starting to slowly convert all the chassis bolts to titanium.

Yeah, those kits are the way to go. I tried a DIY plating and while it was fun to learn and try out, in the end I got a Nickel Wurks kit from Spec Bolt and that was the best bang for the buck.

I got to admit, the nickel wurks kit looks really good!

I bought the nickel wurks as well in the past. Solid stuff!

Less weight on the bike, more in the box? Seems fair Grinning

Not really, when I ride a Japanese bike and still need the 12 and the 14.

Well I hope that 13 doesn't slow you down too much.

You nailed it. I have 3 ktms from 2012 up. Hardware hasn't rusted and i dont coat with anything. RUST must might be because of a brute on hardware or chemicals/water quality during washing

I sometimes do!

Fwiw I usually use torx instead of hex on the bolt. The torx slots seem to be a tighter fit and that may prolong the life of the coating some.

And quality metric tools. Always. Torque to spec. Always. Loctite where needed. Always.

Using the inside torx seemed like a bad idea to me at first but for the bolts that are a low torque number which is the majority of them this actually makes sense cause the outside where the bolts get tightened are the ones that I see getting rusted. I'm doing a build now and will give this a try when I start to go around replacing bolts. The kit I bought doesnt have the m8x40 and m8x50 which is the size you need for the triple clamps nor did it have the m8x20 for the fork lugs. If anyone knows a kit that has those sizes included please let me know.

Yes! I think the smaller contact area of the torx makes for less corrosion. I bought the Bolt Pro-pack set a few weeks ago. Havent recieved it yet, but if it shows up the next few days I’ll report back to you.

If you are really desperate, go to KTM’s sparepartsfinder and find the bolts you need. Most KTM dealers here in Europe usually have a selection of nuts and bolts for the bikes availible. I bet yours have it too.
