The Motobatt has been on my Monster since August 2012 and still going strong, this is only (so far) bettered by the original Yuasa which lasted from 1997 to 2009. So thinking twelve years was very good I replaced it with another but that only lasted the three years in between so switched to the yellow ones.
As for the leads, they made a massive difference on my 900 giving a much faster spin up and therefore instant firing instead of the previous steam engine impression when turning the motor over.
Exact UK do a kit and Stuart will give a discount to UKMOC members if you contact him first PayPal as a gift payment.
Personally I had the parts at work so made my own for all the power and ground (earth) leads.
As an aside Stuart also discounts the Exact timing belts which give an extra year over the Ducati ones making those services a little cheaper.
