Product did exactly what I needed it to… it has a place I could drill a hole to safety wire my bike. I found it a bit hard to get on, but it does fit my 2018 KTM RC390 perfectly.

My KTM RC390 is no longer having high temp issues even in worse traffic conditions. Thanks to this 1.6 Bar radiator cap and the new Spal radiator fan that I have installed.
Highly recommended and a must have for all KTM 390 owners.
Thanks Greg and team for this wonderful product.
Not that bad
