Garage Build: 2018 Suzuki RM-Z450

RacerX TV



The 2018 Suzuki RM-Z450 isn’t far off, but it is in desperate need of a few updates to stay relevant.

The front fork was atrocious, it was heavy, and the motor was just a little bit down on power compared to its adversaries. Oh, and an electric start would have been great. The 2018 RM-Z450 offered changes, but the improvements were marginal, the weight didn’t change much, and it still had a kickstarter. We made it our goal to make the fixes we could on our own.

    I hope Suzuki sees all of this critique and what people do to their bike to make it better and improve that to the next model, for example the linkarm.

    That is a sweet bike, I had a 16 rmz 450 and I liked everything about it except the air fork it had that year but other than that it was a fun bike to ride around!

    Is that a new cover on the tank? Or just a decal to hide the blue?

      Crawler_Freaks Considering its the same engine as last year, just as good if not better than a Yamaha. (had one before I got my yami)

      I have a 2014 rmz450 and it has rolled the hour meter 3 times. Only kept valves in spec and changed the oil religiously. Replaced 1 intake valve from shimming
