This addition to the vSystem and Mark7 Universal Kit increases oil capacity by eight times, from 50ml to 400ml, and should give you 4000 to 6000 miles between refills (depending on your flow rate setting). This is an ideal addition for any biker who will be travelling long distances, or for any biker who just can't be bothered refilling the system very often!

(If the Magnum isn't suitable for your bike why not try a Scottoiler "Lube Tube" flexible HCR instead)
