In the engine department, each utilize liquid-cooled Parallel Twins, the 670cc engine of the CTX700N with a small displacement advantage over the 649cc mill of the Vulcan S. Honda went the undersquare route with a 73mm bore and 80mm stroke whereas Kawasaki went oversquare employing a larger 83mm bore and additional compact 60mm stroke. This makes for distinctively totally different engine characteristics, that we’ll bit on before long. Compression ratios area unit nearly identical, the Honda sporting a ten.7:1 quantitative relation to the Kawasaki’s ten.8:1. each motorcycles supply a six-speed gear case and utilize a sequence final drive. Suspension arrangements area unit similar, every equipped with a 41mm fork and single rear shock. The Vulcan S runs an in. larger wheel up front at eighteen inches, however each use a 160/60-17 arrangement on the rear.

Out on the road we have a tendency to enjoyed the surge of power delivered with the primary crack of the Honda’s throttle, and off the road the CTX has a grip on the Vulcan. Throttle response is immediate and gratifying, as supply on the CTX700N is crisper and cleaner than the Kawasaki’s additional abrupt throttle response and choppier fuel delivery. a visit on the MotoUSA dyno confirmed our seat-of-the-pants assumptions. The 2015 CTX700N delivers forty lb-ft of torsion at 2900 revolutions per minute and stays therein vary till 5400 revolutions per minute, peaking at forty one.19 lb-ft @ 4200 revolutions per minute. The Honda’s powerplant reaches its peak forty three.04 HP @ 6100 revolutions per minute on its thanks to its 6600 revolutions per minute ceiling.

The Kawasaki Twin generates the next peak torsion output of forty two.43 lb-ft @ 5700 revolutions per minute, however it doesn’t match the CTX on very cheap finish. The Vulcan doesn’t hit the forty lb-ft of torsion vary till 4800 revolutions per minute, however, the 649cc Kawasaki engine revs abundant more than its Honda rival. The result's hundreds additional HP, topping out at fifty five.9 HP @ 7500 revolutions per minute on its thanks to a nine300 revolutions per minute single out. high finish is wherever Kawasaki’s call to travel with Associate in Nursing oversquare style pays dividends as a result of long when the CTX700X faucets out, the Vulcan S continues to be revving.

The CTX700N is ok as long as you retain it in its happy place within the low- to midranges, however it hits the rev circuit means earlier, therefore you’re shifting plenty additional therefore than on the Kawasaki. In sixth gear on the Honda there’s a scarcity of roll-on too, and if you’re on a pike with a seventy five mph regulation, you’ll be gritting you’re teeth obtaining by semis whereas it slowly builds up steam. Conversely, the Vulcan S provides lots of passing power, even within the higher revolutions per minute vary of fifth and sixth gear.

“The CTX700N engine contains a nice quantity of pull the initial application, perceptibly snappier than the Vulcan S. The rev vary is restricted to keep up that pull although, and drop off is dramatic before reaching the line, that comes quickly. gear looks to chop out so much ahead of time, and power shuts down suddenly if you tip the needle past the rev limit. In observe I found myself keeping the CTX a gear more than the Vulcan S at similar speeds to confirm there was one thing out there after I required to pass,” same MotoUSA Associate Editor and fellow check rider Byron Wilson.

Since you’ll be running through gears additional often on the Honda, it’s lucky the CTX700 gear case shifts swimmingly and lever pull is light-weight. Gears fall under place quietly with very little fuss. On the Vulcan S, the transmission’s gear ratios enable riders to urge the foremost out of each shift, however engagement isn’t as clean because the Honda’s. we have a tendency to did appreciate that sixth on the Vulcan S is less assailable than sixth on the CTX700, that acts primarily as Associate in Nursing overdrive.
