    dB Customs Carbon 173hp Katana

    Recent build we just completed that is going to a customer in Arizona from dB Customs, with a Ray Mancini 173hp (countershaft hp) 1260cc engine. All paint, no vinyl decals. Any questions, just ask away ....

          Beautiful bike!

          And I'm guessing that $16,500 is low.

            What are the carbs? Are they the RS 34 flat slides that I read so much about here on the forum?

                So is the tank real CF? Or is it CF painted? Or Wrapped maybe?

                Great work. The only thing I would do different is to hide or black out the reg/rec and fuse box.

                    I expect that engine alone is more than half of your $16,500, with the fancy wheels and suspension eating up the rest of it before you even touch the chassis and bodywork.

                      That's fantastic, love it! Is the tail piece/seat the carbon item from Webike in Japan? I got to see one in person some time ago and they're very neat pieces of kit although out of my price range. What brand are the pipes also?

                      I love that it still looks just like a Kat

                        Really like just about everything about this build!

                        3 questions.......... Is there no where discrete to place that $15 stock horn?

                        Looks nice without a cooler but what happens in the AZ summer with a 1260 motor?

                        What's the distance from the bottom of the header to the road when both wheels are on the ground?

                            Some more pics and tiny bit more info on this beautiful Kat.

                              Without a Series R/R or a cooler, I bet it will get very hot. Looks like the stock R/R and stock igniter.

                              It might have been a nice touch to use a Dyna 2000 that has both a rev limited and low RPM retard to improved the longevity of the starter clutch.

                              On top of all that he is using small LED blinkers, and we can probably assume a LED upgrade in the headlamp. Poor little stator probably will not last too long.

                              That looks like a 4:2:1 header; it would be nice to see the full dyno results with hp,torque and AFR
