Using the draggy system. Very user friendly.

I have managed to get low 10.40s with aprox 220whp. Traction off or at lowest setting. Rider mode and 2 in compression. Bike probably can go quicker with better skilled rider than me.

Hi!

I haven't ridden my H2 SX much this year, just one practice session and two rounds of the drag racing championship while my other bikes were broken.
Last year, my best result was 9.271 on the race timing system, with a dragy time of 9.24. That was last September, and the weather was dry and cool, perfect for the H2. Power was around 245-250 hp at the wheel. The gearing is 18-42, and the tires are 190\ 50.
This year, I made some minor changes. I replaced the subframe with a carbon one, installed a carbon front wheel, replaced the rearsets, added a butt support (all this helped to remove about 3.5 kg of weight), and installed 19 front sprockets (which shortened and raised the wheelbase and ground clearance). I also adjusted the rear suspension settings. I continued tune the launch control settings in WRT. All my rides this year have been hot and humid, with rain literally following us at every race. These are the worst conditions for the H2. I also reduced the power, as I knew these conditions weren't conducive to record-breaking runs, and I'd already gotten out of the habit of launching on a standard-wheelbase bike while racing my long GSXRs. I think the power was around 225-235hp.
On average, I've been doing 9.3-9.4s this year with these settings. But in one run, I managed a slightly better 60f than last year, and I ran the quarter in 9.255s. Dragy registered the same 9.24s. I'm sure that with more time and practice, it's possible to do 60f in 1.5 seconds and get 8.9s on a standard wheelbase.

Hi! I'd like to share some new achievements in the world of drag racing on the Kawasaki H2 SX. We recently had a track day with favorable weather for the Kawasaki, and I made some modifications and tested them on the track. The main one was using E85 fuel. It was my first time using it, and it was an interesting experience.

My best result so far was 9.136 on the timing system and 9.11 on the drag strip. I'd like to say that the bike's power has noticeably increased, especially in the mid-range. I had to reduce the bike's power in first and second gear every run to combat wheelie, since the bike has a standard wheelbase. And judging by the logs, I never managed a clean run without wheelie and shifting at the right moment, like I did last year. Well, I guess I'll have to try again and get better accustomed to this bike. From what I can see, breaking the 9-second mark isn't the bike's problem, but the pilot's.

I'll also add a link to the video; it's in Russian, but you can turn on subtitles in your language.

Awesome man! Looking at the 60 def going to equate to a huge gain in the 1/4 when ya can get it to stay down and put the power down and out. I played with my stock h2sx using launch control and the 3 settings the other day, ill tell ya its rough for me. But lots of fun.
