Ah...Did some more research on aftermarket 4-4 exhaust on the cb1100, and I found out the "third" version of the Endurance pipes are actually made by a company called R'S Gear. Japanese made. They are claiming some significant HP and Torque improvements, across all RPM's. HP goes from 77 (stock) to an even 90. I think they are the best sounding of the 4-4 pipes, based on limited sound recordings via YouTube. I think they also look slightly better than the Endurance Hi-Power Fours: http://japan.webike.net/products/20366036.html http://oneveryotherstreet.blogspot.com/2012/08/r-gear-classic-for-honda-cb-1100.html They are also more (ooof!) expensive...
Are you sure you didn't mean 87 HP stock? Pretty much every article I've read mentions that figure. Or are you talking at the wheel? EDIT: Just opened the 2nd link and saw the dyno reading of 77 stock, so at the wheel.
Def the best sounding. And adding 12hp is nothing to sneeze at. But WHEW! 27% of the price of the bike :eek1
Exactly what I was thinking. :eek1 Those are beautiful pipes though and the gains are nice. Why is it everything I always like is always the most expensive things on the planet? Thats the first dyno graph I have seen. Notice how the torque comes on very very early. I bet you can ride this thing around all over the place in high gear and seldom downshift. The more I look at the Cb the better I like it. Its just such a clean design that appears to ooze with simplicity and quality. Whats a Kg of torque? Why doesnt the lines cross at 5250 rpm? Seems odd to me.
The torque and HP lines crossing at 5250 is an artifact of using specific English units for both;use any other units and this doesn't happen. The torque unit is probably kg-meters which should really be kg-force-meters since kg is properly a unit of mass, not force. Actually newton-meters is the proper unit of torque in the metric system. - Mark
No kidding. There are plenty of visual things about the CB1100 that get me fired up, but that torque plot is freakin' awesome!
Thanks for the explanation and this is why I hate the metric system. I still operate with cubic inches, feet, yards, and foot pounds.
Yeah, on paper it looks pretty darn good to me stock. I bet it would satisfy most of us. I still have not fully digested that a set of pipes could cost right at 2700 dollars. I mean this makes HD stuff look cheap. This engine is very mild in stock trim. I have searched the entire internet (LOL) and I can find much information from our brothers in Aussie land or in Asia that modify these things and talk about them. I dont know if they dont sell well over there or what. When these things finally get to America I bet there will be a ton of information on mods, likes, dislikes, how to improve them ect..... The fun can be far off for some now.
I don't really get the impression that the CB1100 has been a big seller to date, although I'm guessing that it's done better in Japan than in Australia. Which causes to me to be all the more surprised that Honda has finally decided to sell the bike in Europe and North America. Perhaps it has something to do with the success of the Triumph Bonneville in these markets? I really don't know. But the timing does seem to be right given the fact that the retro market appears to be doing well, and if anything, to be gaining momentum. Just the same, I don't want to over analyze things and would rather simply relish in the fact that they are finally going to make this bike available here in the USA. I get the impression that many within Honda are particularly proud of the CB1100 and what it represents. Not that they aren't proud of every model that they end up releasing, but some models just seem to be more of a stretch for them than others from a logistics standpoint. I got the same impression when it came to the Hawk GT. It's almost like the guys who design and build the bikes get a chance to do what they want to do every once in a while regardless of what the marketing team or the accounting folks think. The bikes that strike me that way are typically the true gems in my eye.
Here are the R'S Gear "Wyvern" 4-4 pipes. They are pretty...and pretty expensive. They are $2600.00 USD before freight. You can now see why Honda went with a 4-1 pipe. A 4-4 pipe like these would have made it a 12,000 dollar bike. Quite a jump in performance, if this chart is to be believed.
*sniff* I made a bad business decision. *sniff* If he knew he wanted one for himself, he should have left his order alone. Or ordered only those units he was planning on selling. Either way, he likely runs his shop emotionally, not logically. I wouldn't pay the for off-the-shelf parts. For that or less one could get custom fabricated parts. Seriously, likely for half that or below some decent shop would fab, coat, and fit the parts.
And look at the horsepower line on the graph, nearly a straight line building power in a linear fashion from idle to 7 grand. No wonder some think they are boring to ride. Theres no high rpm " hit" like other bikes. To me it looks like an easy fun ride.
