That 105mm BigBoreKit is the weapon of choice for DOHC-Boxer power-enthusiasts.
It is the only way for HP2S owners to keep their bikes in competition with tuned R1200S bikes like mine. In fact, if a HP2S is tuned well, this bigborekit will give those bikes an edge.
But the R1200S imperium will strike back and we'll see how the countermeasures will work.
Or to say it with ZZ TOP: ..... but I'll be back for you Jack and let the machine speak
And if you ask why the trade with this kit will be delayed until fall 2011: Before those kits reach customers' bikes, they will be tested in street bikes as well as in rough used racing bikes for a longer period over thousands and thousands of Kilometres / miles.
Customers shall receive a good product and not be misused as test pilots.
Kurt Roesner and also Woesssner built up their good reputation for quality and for testing their stuff before selling it.
