Description

We're raising the bar - excited to debut our CenterFlow design, the new #1! Now available!

A match made in heaven - you gotta have a thermostat so your engine can heat up and run like it was designed to, and what better place to run all that nice warm coolant than C3 Heated Bars, right under your grips to keep your hands nice and toasty!

Two products that make a very noticeable improvement to your snowbiking experience and that you definitely want anyways, why not bundle them here and save up to $40?

If you have questions, please check the FAQ tab as well as take the time to learn more about each product here {heated bars + thermostat } and when you're ready, choose the options above and get ready to ride - both your engine and your hands will thank you! (for instance, you'll learn that the bars can work with any bike but are 1 1/8" diameter "fat-bar" so be sure to look into risers if you're on a 7/8" bars bike (most Honda and Kawi))

Also recommended - the Trailtech TTO Temp Gauge. Add it easily on this page!

This includes everything you need, like bypass lines and return connections.

We're expecting a high volume of orders for this product so please bear with us if there is a delay arranging your shipment!

Please note: Some housings in some colour options are scheduled for machining but will likely not ship for 3-6 weeks. If your order is time-sensitive, please ensure the colour thermostat you choose is not marked with the big red X.

FAQ

I heard it's bad to dead-head the bike's water pump?

Where did you hear that??? ;)

4 things:

A C3 thermostat + bars setup can never be deadheaded. Our thermostats are built to our custom specifications with a small bleed hole, so there is a built-in bypass system at all times.
Even if you could, "dead-heading the pump" is not a swear word or even a bad thing at all. Ask anyone who's worked in industry - it's a very common and very widely used method to throttle centrifugal pump flow and control complex systems.

The reason that you may have heard as a warning against deadheading pumps is if the same liquid is churned around in the same space for an extended period of time (typically hours and hours straight), the friction will eventually build up enough heat to straight-up vaporize the fluid ("cavitation"), and those pockets of gas are indeed bad for the impeller and bearings. There are some applications where this is a legitimate concern, but clearly that's not the case in a motorcycle engine scenario where any liquid friction heat is negligible (to say the least) compared to the internal combustion occurring in the cylinder inches away! And it is ESPECIALLY not a concern in a system where the thermostat itself inherently acts as a safety control valve, sending up to 100% of coolant flow through the radiators if the coolant temp gets even remotely close to boil point. So all good! At least when you're talking centrifugal pumps like on bikes ("positive displacement" type pumps, that's a different story)

If for some reason you are still concerned, with the valve conveniently located directly ON THE HANDLEBARS with all your other controls, you will have no problem maintaining a perfect level of warmth on the fly without ever closing it entirely, if that is what you choose!
If for some reason you are still scared or apprehensive, we will add the fittings for you to elegantly plumb in another bypass circuit to your next order for free.

What about "hot spots"?

See above about A) the optimized "bleed hole" ensuring the proper slow circulation (never stagnant), and B) the cylinder of course heats up all coolant uniformly - definitely don't worry about "hot spots" in C3 systems.

What thermostat should I get for a ______?

At the top there's a brand selector, with every model listed where we have a purpose-designed direct-fit kit. If your bike is listed, you can choose it there and select your options.

If your model is not listed, please choose "my model is not listed" and check the "Generic Guide" tab here for guidance on the other options.

What opening temp should I get?

With a 90C / 195F 'stat, the bike will typically run 80C - 90C (180F - 195F) all day which is totally ideal, just like summer months. It's great for performance and reliability; there's no reason not to. Thus I always recommend 90C / 195F.

We're not big 2-stroke guys, but often those folks prefer a little cooler, like 80C / 175F.

Another situation where you might consider a 80C 'stat is on a highly modded big-bore bike that you know produces tons of extra heat.

Does the thermostat fit a Trail Tech temp gauge?

Yes! Every model was designed around the Trail Tech probe. Highly recommended accessory.

Do the bars fit my bike?

•WILL NOT fit 7/8" mounts •WILL NOT fit bar clamps that are one-piece solid "bridged" on the underside (some Husky FX and KTM XCF) (replacement risers available here)

•WILL fit stock risers on most other popular bikes •WILL fit with all handguard styles, to our knowledge •WILL fit with one-piece TOP clamps

How do I force the air out of the handlebars?

It will happen on its own. The pump pushes fluid through the path of least resistance - this forces fluid INTO the bars with some PSI of positive pressure, displacing any empty space. Remember, there's internal passages for even heat distribution so the fluid has to reach the top end of the bars to make it to the other side. Then the air will eventually rise to the tops of the radiators.

So, to answer the question, just run the bike up to temp with the valve to the bars open, then top up the coolant level in the radiators. As always, be sure to follow your owner's manual, this includes keeping an eye on the coolant level after each ride too.

My 2010-2013 YZ450F has the same engine as a 2014, can I use that kit?

Strictly speaking, no, the thermostat is not compatible. That is because the engine mount is juust in the way. That said, we have had plenty of customers who chose to make it work with some modifications to the engine mount bracket.

We can't "wholeheartedly" recommend it, but you may wish to go this route! If you're not comfortable with that, the Generic Straight with 22mm housing and 17mm return is your best bet.

Can I get a spare __ degree thermostat to try?

Yes, find it here.
