Track prepped
I don’t know how much my bike weighs now with some of the weight measures I have taken. Stock the bike weighs 462 lbs non ABS model.
Stock exhaust 11lbs......Delkevic full system 3.5 lbs Stock battery 6.4 lbs.......after market lithium ion battery Less than 1 pound, so we will just say 1 lb. Stock handle bars solid metal weight unknown.....Vortex clip ons much lighter Stock rear sets and passenger pegs weight unknown..... after market rear sets much lighter. I still have the stock body plastics on for now. So I will say my bike is around 350 lbs or less! Weight makes a huge difference with the smaller bikes, the less weight the better on the track! |

I took my 2009 250R from 372lbs down to 310-lbs with tossing pretty much all stock parts except for frame, tank, engine, carbs and seat. And also includes chopping unnecessary parts of frame off. Lighter wheels & tyres. Hollow chromoly axles. Ti and alloy nuts & bolts liberally sprinkled around.
Was gathering data on what’s possible with 400 to determine if I want to build one for next season. No one inspects or protests 250s so I can bend rules liberally. But Ninja 400s caused quite an upset this year with times that puts them in top 5-10 of every class! Anyone with 400 seems to have spotlight on them. |

I appears Kawi already did lots of weight-optimization, so I don't think I'll be able to chop off as much weight from 400 as I did on 250. Are you still using 150 rear tyre? Seems lots of folks go to 140 to better match 4.0 rear wheel. |

Yes I am still using a 150 rear on the 400, some of my friends are using the 140 on their R3s and 400s. I will try it when my current 150 wears out. I will be using the 140 on the N250. |

My 300 race bike was 291 lbs with the fuel light blinking. Curious to see where my 400 comes in at
