Very very nice,
I read that suzuki factory forks rock too.
Can you please weigh the bare frame with the swing arm as is now.
Thanks! Yeah really excited for this project.
Yes I will weigh the frame and swingarm. The rear suspension feels pretty heavy. Purchased the fork tubes today, “SHOWA”.
But yeah I’ll start a build thread for this bike. Trying to do my homework to figure out which motor but probably going with that QS180. Need to look at the Golden motors as well. First priority is to get this to a rolling chassis, already purchased all new bearings - swingarm, head tube, upper suspension etc. from allballsracing.com.

I did some peeking around at 138 #s. 180 #s are pretty much non-existent.
From the #s of other motors people are running I would estimate 3x the rated power?
like 24kw or more?
Yeah I found a couple videos on YouTube for the QS180 but wasn’t in English. I believe that motor came out this year or maybe late last year so there’s not a lot of info out there. I normally don’t like buying the first generation of anything in case there’s something that needs to be worked out in the engineering. That’s why I’m trying to find some real life feedback for that motor before purchasing.
There seems to be a good amount of information for the QS138 dating back for several years. Seems like a great motor for more of a pit bike set up but maybe not a full size 250 or 450cc frame because of the weight.
This bike RMZ 250 from factory has around 40-ish hp so I would like to surpass that, I’m not sure if that’s possible with the QS138 without overheating or worrying about temps.

In my rmz 250 I used the 138 90h with a bac8000 maxed out at 32kw.
Now I am building a crf450 using the QS 180 90h with a fardriver 961800. The goal is to have 45kw +
Great thanks for the feedback! How is/was the temperature with the QS138 with 32 kW? Do you have a build thread or any pictures?
Yeah 45 kW sounds real nice! I’m aiming for somewhere in that ballpark, would like 50+ horsepower. Been looking at the fardrivers as well. Maybe the Fardriver ND721200.
