about this

Stage 4 is the premier tuning package from MotoCult for the Janus 250 model line. This kit includes everything you need to turn your stock 229cc engine into a very powerful and reliable 250cc beast. This is not a race motor, MotoCult designed Stage 4 to deliver smooth and predictable power throughout the entire RPM range. Imagine reaching speeds of over 75MPH with ease, yep, it is now possible with this kit. The exhaust for this kit fits perfectly to a Halcyon 250 but it will work on a Phoenix or Gryffin with a few simple parts from Janus. Want even more power? Add this performance carburetor package.

Don't forget to add the crank shaft seal installation tool to your cart

This kit will greatly increase the space between shifting points.

Stage 4 shifting points:

First to second gear 0-23 MPH

Second to third gear 23-43 MPH

Third to fourth gear 43-63 MPH

Fourth to fifth gear 63-73 MPH

Fifth gear 73-80+ MPH

Moto better with MotoCult

This kit has turned my Janus, Origin-1 into the bike of small displacement dreams! It has improved performance in every measurable way. Quicker exceleration, higher top speed, rins smoother with the added Nibi carb (the + in stage 4 "+"). The sound through Devin's performance exhaust is deeper, stronger and makes me smile at every start up. Fuel milage is off the charts compared to stock. Before the stage 4+ install, 60+ mpg was about as good as it got. Now I regularly get 70+ mpg with normal riding including hills and 65 mph speeds. When I just leave to go for a ramble, running 35-55 mph I have got as much as 75 mpg. I cannot say enough about this kit. You think your Janud puts a smile on your face now? Install this kit and your face will hurt!

Miles of Smiles!!

I have been riding for over 15 years, and I've ridden everything from older Sachs mopeds to Harleys and adventure bikes. Without any reservation, I have not been this excited to jump on a bike in a long time since the Stage 4 Plus was installed on my Phoenix.

For those considering the cost: The investment is worth the miles of smiles you will get out of the updates in both the performance and operation of your 250. Life is too short to delay the massive increase on the fun scale when you take that first ride on your bike after the Stage 4 Plus facelift!

Fun Factor: It is totally off the scale in terms of the changes to the bike. After ripping around on the first "post-Stage 4 Plus" install, mechanical upgrades unlocked the true spirit of what the Phoenix was always supposed to be.

And while the Stage 4 Plus kit is outstanding, I would be remiss if I didn't mention the other factor that makes Motocult such a great company; exemplary ownership.

Regarding support and troubleshooting: Devin was super responsive to any questions or concerns I had and provided a great deal of help over the phone both before and after the installation.

Devin is an all-around great person, and it's refreshing to work with a professional who is passionate about what he does.

As a former small business owner, I can appreciate the time, energy, dedication, and passion that go into not only creating a great product but also providing top-tier support for it; Devin has achieved all that and more with the products and services he designs and supports at Motocult.

Janus 250 Stage 4 Performance package

I am extremely satisfied with the Janus 250 stage four performance package that Devin Installed on my 2020 Janus 250 Gryffin. The Moto now has strong broad power band throughout the RPM curve Delivering true, 250 cc power and performance; while delivering 71 miles per gallon on the back roads of Southwest Wisconsin. If you find your stock, Janus 250 disappointing in power and performance I strongly suggest contacting Devin at Moto cult, get the stage four performance package installed, and then you will truly look forward to every ride on your Janus.

The Spirit of Rambling

The stage 4+ kit turns a great bike into an incredible bike. Better starts, instant throttle response, effortless rambling, I could go on. MotoCult manages to fully capture the spirit of what the Halcyon is explained to be. To be able to effortlessly cruise around without the throttle pegged is a huge win. To say I had to almost relearn the bike is an understatement. The difference is night and day and I couldn’t be happier. Not only does the aesthetic continue to please, but the sound, oh the sound. The exhaust makes the bike sound how you’d expect with how the bike looks.
I can’t wait to see what else Devin comes up with.

227 REBORN

After reading the performance improvements promised with adding the stage 4+ upgrade to the Janus Halcyon 250 I knew I wanted it. Let me tell you, all claims have been confirmed. Devin and MotoCult deliver as promised. This bike runs and sounds as it always should have.Every twist of the throttle and gear change is a pure joy. The exhaust note is sweet and pleasing from idle to full throttle.Throttle response is immediate with 0 rev hang.Can’t say enough about Devins professionalism and quality of his work. In this day and age it’s refreshing to deal someone that does what they say and truly cares about the product they put out. Thanks Devin and MotoCult. I’ll be watching for what’s next!
