Description
Additional photos are available here for your perusal.
Born from the ashes of an original 2005 Ninja 250 whose engine gave out, came this creation – a Ninja 250 body and chassis with a modern Ninja 400 engine.
To properly convey the process of this build, we’ll defer to the seller: “This started as an original Ninja 250 with 1136 miles and a bad engine, I sourced a wrecked Ninja 400 and carefully combined the two. To my surprise, a lot of the bike wanted to go together. The goal was to create the bike that Kawasaki should have built. I always had a soft spot for the ‘brick ninjas’ and this one is my greatest creation out of the 4 I’ve owned over the years.”
This example is VIN: JKAEXMF135DA12021. The seller purchased the original Ninja 250 via Facebook Marketplace in January of 2023.
The odometer has been replaced. The seller states there is 20,299 miles on the engine and 2,678 miles on the chassis.
Maintenance:
