Nice man I’m on a 400 now might be looking at the zx4rr. What tires are you running?

Hey Garry!
Nice bike! I love my Ninja 400R! I'm not sure what you're planning on doing with the ZX4, but its a completely different kind of bike. If you're gonna do more street/canyon stuff, I'd actually recommend that you stay on the 400.
It took me 4 track days to get comfortable for with the ZX4 and I was actually running slower lap times until this past Monday. The lack of torque and the high gearing on the ZX4 made it really sluggish out of corners unless you're in the upper 3rd of the rev range. I had to really change the way I ride.
All of my mods are on the descriptions on my videos. I'm currently running Pirelli SuperCorsa SC2 front and SC3 rears. The fronts still have plenty of meat left, but I burned through my rears in 3 track days and had to flip them for this 4th one. Conversely, I could run the same tires on my Ninja 400R for 1.5 seasons!

@@autojunkee Okay cool man that’s interesting about the lap times and tire wear! I’m currently riding like 90% track I was actually there at thunderhill east last Monday 😅
Love the ninja 400, still learning a lot on it but also miss the performance of my previous zx6r. Debating on whether to put some $$ into the 400 or invest in a slightly faster bike with better components. What kind of lap times were you getting on the 400 if you don’t mind me asking?

Oh, cool! We should hang out next time I'm out there! I always like more track friends!
My fastest laps on an N400R at Thill East CCW were 2:14-2:15 and the fastest lap I got on the ZX4 was 2:12. ua-cam.com/video/J9CKNJqTpv0/v-deo.html
I found the N400R just easier to ride overall, whereas the ZX4 really has to carry a lot more corner speed. The bigger pistons of the N400R really pulled me out of corners. Winning times for an N400R was around the 2:10 mark, last time I checked, with Rocco Landers destroying that time. He did a 1:56 in full race trim.
ZX4 definitely has more potential, but the N400R isn't slow by any means. Let me know if you have any videos to share from Monday!
