525 RFS cam chain tool.

Recommended Posts

Hi, I'm about to purchase an 05 525 exc. It will need a top end soonish and to do this you have to break the cam chain. KTM sell a tool for it, it's not cheap. What are the cheaper options for this? Also needs to be able to reinstall the pins. Cheers

I used the motion pro for years. Harbor freight has a copy.

If you can get the plate on without binding the pins, and swedge each pin .004 or .005" (about .1016mm)  they work okay. The plate is a press on fit, pin swedging adds to security. Some riders will put a steel dolly on the inside and bang away with a hammer on the chain and sprocket. The KTM tool works so well, you cannot see the replaced master link.

Universal chain tools do the job if careful. Pack the chain galley with clean rags before you start this project as the link can be lost in the motor.

Bicycle chain breaker.  Cheap and available at a bicycle shop.

This is from a new zealand site that sells semi cheap generic parts and tools. It says it does everything I need it to do, but how well is the question. It's cheap enough thoughScreenshot_2017-05-07-09-11-35.png

Just remember to shove a rag around the cam chain for when the link/pin drops off the chain... :banghead:

If you have a cycle gear near you they sell a chain breaker, rivet kit.  Usually 40 bucks.

Is this the same kit as the Tusk Standard Chain kit? This, the Tusk and the $20 eBay kits all look identical. Looking to buy one for my 450 RFS as well.

Pretty much (maybe even exactly?) the same. I used the tusk chain riveting tool kit on my 540 cam chain a couple years ago. I had ordered 2 rivet links (they're only +/-$5) in case I screwed up, but everything went as planned the first try.

The KTM tool is $150 from RMATV, if I thought I'd be building RFS's on a semi regular basis I'd have probably bought it, but as it stands, I've only rebuilt the 1.

That looks identical to the one Cycle Gear sells for $40.

It does look identical but if you read reviews on some of the eBay ones they're terrible quality, where the Tusk reviews are kind of mid-range, then of course the KTM tool gets the best reviews. I would assume if they were the same kit they would have similar reviews concerning quality but they don't. RM sells the Tusk kit for $35 so that's the best route to go probably unless you're rebuilding engines a lot.

All of the cheap kits are made in China, Tusk included. The only benefit I can see to the Tusk kit is that RMATV will stand behind it if it fails. I think the difference in reviews you're seeing is likely due to the difference in customer base. An experienced motorcycle mechanic (even just your average home garage guys) may be at least slightly less likely to break a tool by using it properly, while those that could break a hammer and attempt to fix a blown engine by installing new grips and black spray paint are more likely to buy from Amazon, Aliexpress, Banggood, etc. Plenty of reviews of broken Tusk tools too. Get which ever one helps you sleep at night.

If someone breaks a chinese chainbreaker tool on that wienie cam chain they should take the bike to a dealer.
