Radian EXR: The Future of Enduro is here!

[Anders]

If this is going to be road legal, then it would be at the top of my list as my EXs replacement.

I don't ride my EX on the streets, but this surely looks interesting anyway.

 

[Karinshi]

i dont get why it has less range with a larger battery than the stark

 

[Erwin P]

Different claims i suppose.
They are testing in the Netherlands and out here it's just one big sandpit.

In the end all elektric motors kinda are as efficient as any. So battery size translates into range.

 

[Karinshi]

It looks like a good bike, it has the features many people want and have requested. Some want certain characteristics, others want different ones, and it's good that the market is growing and there are more options. It's also important that they focus on good customer service, have a good capacity for resolving problems, and have spare parts readily available... It's not just about having a motorcycle that works well, it's about all the work involved in building a strong company/customer relationship and keeping things running smoothly and quickly.

I think waiting almost two years for the launch is too long, and by then technology will have advanced, and something better could be released shortly after, potentially putting them in a difficult position.

Personally, I don't see it as an option because I wouldn't use the battery swapping feature. I don't have racetracks where I live, and I don't have a truck to transport the motorcycle, extra batteries, and charger... I'm more of a round-tripper.

I also think it's a bit heavy, and the 125 kg figure probably doesn't include the onboard charger, which likely adds another 5-8 kg.

Nevertheless, I wish this new company and its users every success.

 

[Erwin P]

They are however comming with a smaller battery (same packing size) with less kWh and i believe 13kg lighter. Would have to look at their website for that.

 

[happyinmotion]

I'm glad there's going to be more choices for us all...

... but production in Q4 2027 plus slippage means we might get these in 2028. What's Stark going to have by then? Definitely a bigger battery for the current models. The Älg adventure bike for sure. Maybe the street bike? Maybe the smaller dirt bike?

Yes, a smaller 5.8kwh battery with less cells and same shape will be added, that's cool, nothing wrong in it

 

[Theo]

Yes, by the time they will start producing it, Stark will have evolved. However, if better cells will be available, Radian may take advantege of them, too and possibly use for example 9.5 kWh instead of 8.6.

 

[Karinshi]

The point is, they should sell the smaller battery with the bike directly too, so you can choose between the two batteries from the start. I don't see much point in buying the bike for €14.5k with the larger battery and then having to pay probably another €2k for the smaller one. It should be an option to buy the bike with the smaller battery for around €1,000 less, not as a later option, for example.

@happyinmotion In the enduro sector this is a huge win. The more quality bikes out the better for the whole market.

As for the other bikes you've mentioned from Stark... completely different markets. You'll be lucky to see any of them by early 2028.

For Adv I'd still want ICE.
For street Im keeping an eye on BBM.
For minis, I'd have my kids on an RTR ATM.

that will delay the launch even more, i dont think this bike will be released before Q1 2028... this things always get delayed

My thought is that Stark will probably release a EX1.2 later in 2028, it won't be completely renewed, it will have some minor improvements. The big change will be the battery, probably a minimum of 9.2 kWh with the ability to be interchangeable with the current model (they literally said this).

Sorry, i wont talk or compare about Stark anymore, i think this thread is to talk about the Radian itself, I hope everything goes well

im pretty sure the Alg will come in 2027, Street 2028 and minivarg on 2029

I've not seen an Alg test mule about in about 6 months. About the same time as their new battery supplier came on board. Adding in their current expansion rate from what they want to what they have.... Im under the impression that they are WAY behind on their road map.

I love the cleaver dual battery solution! Tool-free and quick-swappable??? Really???!!!! Outstanding!

Ignore the naysayers who said swappable batteries are too heavy and nobody would want them. Radian-shaped half-batteries are the Radian's answer!

The current 8.4 kWh "InfiniPack Endurance" are good for enduro. The up-coming smaller 5.8 kWh "InfiniPack Sprint" will be the preferred option for amateur motocross.

I wish there was an option to run just one 4.3 kWh 336V battery. This is the preferred capacity for vets, play riders, and Dust Moto. The power can be capped at 40-50 hp in this configuration. I am sure such a pack can be wired up. But can it be centered on the bike? Name it "FiniPack", "MiniPack", or "UniPack"!

I like the bike's design. I burst out laughing when I saw the Alta-inspired sub-frame braces and the Stark-inspired rear end. It works!

Thanks for the KYB suspension and Brembo brakes. No sense saving pennies on dirt bike essentials.

The storage/charger/sandwich/beer compartment is awesome!

Thank you for listening to all of our wishes @Tim - Radian! I am glad that we haven't been airing them out in vain.

Yes, by the time they will start producing it, Stark will have evolved. However, if better cells will be available, Radian may take advantage of them, too and possibly use for example 9.5 kWh instead of 8.6.

I was thinking the same thing.

 

[Philip]

It depends on how they did it. If each "half pack" is full system voltage then it does indeed increase system cost and complexity. If each "half pack" is half voltage and they are connected in series, then the addition cost and complexity penalty is not so much.

For the RE Him-E each "half pack" is full system voltage. The bike basically has two battery packs in it.

Please tell us more. Why would Royal Enfield pursue one strategy but Radian the opposite?

Can RE run with one battery removed? Will it be lopsided?

Not really because the batteries are mechanically load bearing. But electrically yes. And if one battery has an electronics failure, you can run on the remaining one.

 

[Tim - Radian]

Sorry guys! These days were extremely busy, so only now just got some time to respond to your comments... But thanks for all the feedback and kind comments!

I like it. It's a full size bike, which for some reasons the other manufacturers prefer not to make, and it has components from reputable makers.
The retail price is high but if the battery really preserves an 80% State of Health up to 2,000 hours of riding time (read it on their specification sheet of their website) it means that it'll last a very long time and running costs must be considered when talking about dirtbikes. In order to assess the cost of this bike even better, we should know how much that battery pack costs, in case one decides to replace it after those very long 2,000 hours.
I'd like to know about the warranty, too.

Yes, we are offering two-year warranty on the bike. We feel like warranty is important to give some reassurance that we will help you if the tech lets you down (of course we do our best to fix all the faults before shipping).

Ok, the photos don't specify one thing though. As shown, they interfere with the seat so you cannot carry them inside the storage space. I am assuming that this is just how it appears in the photo and that you can carry both these items (1 at a time) in the storage space as you ride. Radian, is this correct?

It's difficult to see in the pictures and renders, but the space in the Smart Storage (airbox area) is really big. We did some optimization with KYB to source the shock type that leaves the most amount of space in this area. This resulted in quite some liters of usable space. So Erwin is indeed right, the modules are designed to be fitted into the Smart Storage.

I don't ride my EX on the streets, but this surely looks interesting anyway.

Yes, it's road legal!

Fair point! We started development with the larger battery size in 2021 (before Stark existed by the way), cell tech has evolved and has increased the kWh value. We're seeing quite some demand for the smaller battery, so we might give that some priority in our development roadmap. By the way, if we bring out a smaller battery in the meantime (no guarantees) and you have a reservation for the current Endurance pack , we can always switch your reservation to the smaller battery.

Yes, by the time they will start producing it, Stark will have evolved. However, if better cells will be available, Radian may take advantege of them, too and possibly use for example 9.5 kWh instead of 8.6.

Yeah, you're right. We are in constant talks with cell manufacturers and will be on top of new cells if they arrive. That will increase the range even more and make the bike even more usable.

Thanks Philip! Can't say we didn't take a look at Alta for the frame-braces . Also, the EXR name is a slight hint to the Redshift EXR. So yes, the Alta has a place in our hearts!
And yes, I've been on EDR for quite a while now, so all comments and feedback were taken into consideration designing the EXR!
