The CRF engine is basically identical to my 2011 CBR250R. It has been used in the cbr250/300, crf250/300L/M/rally; Rebel 300, CB300F, CB300R, CL300, and 250cc variants of each of those bikes for Asian markets. I reckon they've had the tooling money back on it by now.Le_Fromage_Grande wrote: Sun Feb 08, 2026 4:57 pm Because the KLE 500 is a 30 year old design, it probably costs less to make the EX500 engine than it does the CRF, there's at least 4 current Kawasakis with engines based on it
Apart from the engine going up to 300cc and recently adding an LED headlight, the CRF has been basically the same since introduced in 2012.
The KLE however has a brand new chassis and bodywork. The r&d is definitely not yet amortised.
The KLE's engine is used in the z500, ninja 500, and eliminator 500 and maybe also those hybrids, but it has nothing to do with the ex500 and gpz500. Rather it's a bored out ninja 400, which was a brand new engine in 2017 replacing the ninja 300 which was a bored out ninja 250 which had existed since the 1986 gpx250. They definitely got their money's worth on the 250 but I guess the 400/450 might still owe them something.
