Don’t do it, I bought a pair from their website, the mounting holes were off by miles I spent awhile enlarging them with a burr tool, got them to a stage where I could actually thread bolts through, only to realise the bottom left rad inlet pipe is way to long, and the wrong angle. I bought a elbow hose, but even after bending inlet pipe with heat, I’d come to the realisation I’d have to cut it shorter, losing the hose barb unless I got it re-welded. I’ve given up on them. Not worth the time and they feel like crap tbh I don’t care how cheap they were.
I’m now looking at either repairing my old ones or outlaw racing rads from America. The latter is a bit dear but I’m yet to hear how they’d fit the k5. This nonsense has kept my bike off the dirt for months!!!
