Found some interesting specs for the CTX1300 from
Honda Japan website:
84 hp @ 6000 rpm (not bhp)
78.18 lb-ft torque @ 4500 rpm.
Lower
rpm for both hp and torque than the ST. also lower numbers overall
BUT the CTX has higher torque at 4500 rpm than the ST1300 at that same rpm (only about 70 lb-ft @ 4500 rpm). So Honda did what they said they were trying to do... increase torque at the low-mid range... at a cost to overall torque and hp at the higher end.
For MPG: There are 2 numbers indicated for this and 2 methods of measure. One of these is similar to how EPA emissions testing is used in the U.S. to calculate mpg. This is called WMTC in Japan. The other method sounds like they take it out with rider and passenger at 60km/h for larger than 50cc bikes and actually measure mpg.
I found
this web link describes these 2 methods
So running the numbers through a converter/calculator online gives us the following:
Standard test mpg: 63.97 mpg at 37.3 mph (Japan's standard test speed)
WMTC calculated average mpg: 43.5 mpg
For comparison Honda USA shows mpg for the ST1300 at 35 mpg using the EPA emissions calculated method (compares to Japan's WMTC method). I know a lot of you guys with ST1300 get over 45 mpg, and even over 50 mpg in normal driving. I would guess by this that the CTX would be easily capable of the 60+ mpg, and consistently over 55+ mpg at overall commuting type driving in real world situations. So as expected, higher power in lower ranges but lower power overall yet higher mpg. I do think Honda could have done a lot better with this engine and still come out with their goal for this bike.
