considering an H2SXSE+

Post by LIEU910 » Wed Jun 09, 2021 10:00 pm


I am in the process of considering an H2SXSE+. This would mainly be for day rides, scratching around in the canyons, etc. I have a K16GT for touring and two up.

The H2SXSE+ would replace my S1000XR, which I really like, but the lure of a SC bike is hard to resist.

My biggest question/concern is around modification. Specifically, what modifications are "safe" with 91 octane pump gas, and how much power those modifications provide?

Not sure what you think would be a problem? I have filter, full exhaust, and a stage 1 gear and I don't have issues with 91 when I use it.

Most stuff around me is 91-92. Some 93.

As for power, I've never really calculated it out by mods. Assuming 175ish rwhp stock, sprint/full exhaust/flash netted me 210-220rwhp IIRC. S1-gear got me to around 242rwhp, or whatever it says in my sig.

Thanks for the reply.

Sounds like a good tune that is not too aggressive and an exhaust is not going to be a detriment to reliability.

No. Not at all. Vcyclenut has a great tune you can mail in for. Or if you have a trusted tuner near you. If you want to keep it basic, I'd do a sprint and exhaust. I personally would go full exhaust system, but you can do a slipon if you choose.

Hey Man, I’m in the same situation as you. I have a K16GT and the lighter weight and higher horsepower of the SX SE is very intriguing. I hope to get some seat time on a SX SE very soon and I’ll be sure to report my thoughts on it. Unlike you though, I don’t want to own 2 bikes (insurance is a killer here in Canada), so for me it’s one or the other. There are some nice features on the K1600 I’m not sure I want to live without (fuel range, top case, shaft drive, electronic windshield, etc. Plus, I’ve done so many custom mods and farkles to my K1600, that I’ve really got it working well for me. BUT, losing 200lbs and increasing the fun factor are things that really lead me to the SX SE.

I recently sold my 2018 H2SXSE and plan to buy a 2021 S1XR to replace the Kawasaki.

From my perspective you really don't have to do anything to the H2SXSE, it comes from the factory just about perfect. I felt the throttle response in all engine modes was smooth and linear and don't see a need for a ECU flash unless you want to boost HP. Vcyclenut offers a inexpensive flash and it's probably the best flash available so between a flash, sprint air filter and aftermarket can you can probably easily unleash another 15+HP without putting your engine in any danger of grenading.

With that said the riding position is a little more aggressive than the riding position on your XR but bar risers and ABM handlebar kit can provide a more upright riding position. The Kawasaki panniers are cool but inferior in carrying capacity to the XR's panniers. In my opinion the H2SXSE is not really a sport touring bike as much as it is a sport bike with factory panniers. For your intended purpose of day rides and canyon carving I think the H2SXSE is a good option but not all that much better, if any, than your XR. Good luck with your decision

I want to trade my K1600 to someone for their H2SXSE for a week. That would sure help me decide if I could give up some features for the increase in HP and fun.

While I enjoyed my H2SXSE it definitely was not a replacement for my 2016 K16GTLE, it made a great companion bike to the K16 but if I had to choose between keeping my K16 or H2SXSE the Kawasaki would be gone in a heartbeat. From my perspective of owning both bikes at the same time the H2 was nimble but not that much more nimble than the K16 and the H2 was faster but not that much more faster in the usable RPM range where you spend most of your time riding. Now if your goal is to get as close as possible to 200 mph then the H2SXSE is the bike for you because there's no amount of modifications you can ever do to a K16 to approach 200 mph but you can get there pretty easily on the H2 with an inexpensive flash, sprint air filer, aftermarket can and maybe a intercooler.

Interesting perspective. It's a tough choice, wish I had room for all 3 bikes. I'm sure you will enjoy the XR.

Hard to be the mighty K16 for long distance , two up, and stonking grunt.
