Here is the same kit:
http://www.boostisgood.com/RocketIII/index.htm
As you can see, 'if' they still make this kit for the Rocket, it was $5500.
And as others have mentioned, if you can find a better/cheaper start for well under $10k you are saving and then having it installed..
I can say from experience as I have ridden 2 of these that we built back in 2006 when the Rocket was out for a bit. I worked for a dealer up here in Pa. that is well known for their newer Triumph's (not old school stuff).
I used to roadrace Suzuki and Ducati stuff while I worked there. On Sundays I would lead a customer ride using a similar Black/Chrome R3 Turbo.
Our first one we put the Lucifer Orange and black tribal body kit on- that thing stood out over anything, sounded like a dump truck, and could be scary/hairy at times to ride.
It's a big bike but the geometry works, brakes are off thier Daytona sportbike and 320mm discs, and a 240 rear always hooks up...after a good spin up to about 60mph.
Only thing I ever noticed, was when they got real hot, the clutch disengagement could be very very loud with a clunk when in traffic, and they definitely run hot.
It's a unique bike- and the turbo kit here from Boost Is Good (Turbo Connection) is well known as many were done on these. Easy to install kit, simple(useable) boost, and were very reliable.
We sold our 2 R3 Turbo's back in 2006 and 2007 for $15k.....
