Is the XS400 the same as the Maxim?

[Rileypreston99]

Hey guys new here, I’m getting a 1984 Yamaha Maxim 400 from my brother this weekend and have been doing some research on it but can’t seem to find much. Is the XS400 the same bike? I believe this bike is the DOHC. I’ll know more when I get my hands on it. Here is a photo of said bike. Thanks in advance!!

That's a XS400 Maxim, I believe they were only made in 82 or 83 model years, so double check the year. Only the Maxim and Seca has the monoshock rear end, and it's easy to tell which is which. The Seca is more sporty and has a 6 speed transmission, the Maxim has a 5 speed. They're great bikes, and in stock setup you'll have very few issues. My biggest issue has always been the safety switches (kickstand switch specifically likes to go bad)

That is the DOHC 400 engine and as Moonclipper pointed out, has the mono-shock. The xs400 uses duel shocks in the back.

Yamaha made things confusing.

Maxim and Seca are styling packages. Seca is more sporty styled, Maxim is more cruiser. This primarily applied to XJ series, but also to the DOHC XS, but only to the 400.

XS400 was a name applied to both Maxim/Seca DOHC bikes and the older SOHC bikes, which also came in a few styling packages.

So, your Maxim is an XS400 by name, but technologically it's more or less half an XJ (XJ series were four-cylinder inlines).

I am really not sure why they did this. At a guess, they probably did not want to add a twin to the XJ range of four-cylinders.
