RPE Racing 1400cc Big Bore kit

[rperacing]

RPE Racing just released this big bore kit for the Honda CBX. This is a top of the line combination, 74mm wossner forged pistons, forged H beam rods, Cometic HG and sleeves. Sleeves not pictured...

This kit requires machining but other than that fits the CBX without issues. We have ran this kit in many engines without any problems

This kit includes 6 x Pistons (pins, circlips and rings), 6 conrods (with bolts), copper headgasket and 6 cast iron sleeves.
Cost is 2130USD. We can also supply a cast piston option for 1750USD..

Has me kind of wishing I had a engine in need of a complete rebuild. Oh and the money to pay for it, of course.

that's a big outlay cash, for the parts and labor combined you could buy a good used Hayabusa that will leave that set up far behind...

imo a flawlessly tuned and dead reliable cbx doesn't need more hp, it's awesome just as is...better braking and handling is what I really want on my Z, if I want to go faster I just get on my '84 GS1150

You are clearly not our target customer. This is for those who believe a 130+whp CBX is as exciting as it gets.

There are a lot of products for the purists, this one is for those wanting more (not a rational behaviour but who cares ). We know these people exist as some of them are our customers already.

I love a 16V GS btw!

for your opinion.

if money were no concern and I had a two Z's then yeah, one of them being a highly modified 130hp Z would be hoot...I love it when others do it, it's just not practical or rational imo...but then my my wife doesn't think I'm practical or rational having 3 bikes and one of which I will never ride again

Hm, knowing my past propensity for doing stupid things on powerful motorbikes it's likely a good thing I cannot afford such an upgrade.
ie; Doing wheelies with a passenger on a public hyway while passing other vehicles
