KTM 390 Duke R
The KTM 390 Duke R is one of the quickest and most powerful naked motorcycles in the 400cc segment. It is powered by a 398.63 cc engine that generates 46 hp and 39 Nm. It delivers strong acceleration and agile handling, while cruise control adds convenience on long highway journeys. It also offers an adjustable seat height (800 mm to 820 mm), a rare feature in this class that makes the bike easier to adapt to different riders.
The fully adjustable WP APEX suspension gives riders the flexibility to fine-tune the bike's handling, whether for everyday riding or more spirited outings. It has a relatively low kerb weight, which enhances acceleration and agility, making the Duke R feel responsive across a range of riding conditions.

Questions you may find useful
I will be booking the Atlantic Blue 390R next month. I am from Ahmedabad and recently visited the dealership for a test ride and quotation. The quotation they provided is attached in the photo. Before I book the motorcycle, I want to understand what the following charges are for: 1. Municipality Charges: I have never heard of this charge. Is it compulsory? 2. 5-Year Extended Warranty: The dealer said it covers only engine wear and tear. Is this really worth getting? Has anyone actually used this coverage, or is it just an additional way of charging consumers? 3. HYPO: I assume I won’t have to pay this since I am buying the motorcycle outright with cash. Is that correct?
Congratulations on your new KTM 390 Duke R - we're sure you're in for a hair-raising journey. Let’s break down the charges:Municipality Charges: This is not a standard charge everywhere, but some cities levy a small fee at the time of registration, usually for road maintenance or local transport infrastructure. It’s typically a few hundred rupees and is collected by the RTO. If it’s a significant amount, ask the dealer for a breakup or check with your local RTO agent.5-year extended warranty: This is a genuine KTM-backed product, but it’s important to understand what it covers. It’s essentially an extension of the standard warranty, but after the initial period, it usually covers only major engine and gearbox components, not wear-and-tear items like clutch plates, brake pads or consumables. Whether it’s worth it or not depends on your ownership plans. If you plan to keep the bike long-term and keep it stock, then it's definitely worth shelling out the small amount, as it will give you peace of mind in the long run.HYPO: This is a hypothecation charge, which is only applicable if you’re taking a loan. If you’re buying the bike outright, you don’t need to pay this.A couple of additional tips: check if the insurance premium quoted is competitive – you can often get a better deal by buying it yourself online. Also, ask for a detailed breakup of the “handling” or “logistics” charges - if you don't seem convinced by these, tell the dealer to remove them.Overall, most of these charges are legitimate, and some we would even recommend you spend on (like the extended warranty), but it’s always worth asking for a detailed breakup and questioning anything that doesn’t make sense. Happy riding!
I am planning to buy a KTM Duke. Initially, I considered the 250 because the 390 feels scary, and I am not ready for that yet. But with the new Duke, I'm confused between the two. Can you help me with this?
The 350cc KTM 390 Duke finds a good middle ground between the 399cc 390 Duke R and the smaller 250 Duke in terms of outright power. Even though it has over 40hp, this engine is rather peaky which means you won't be accessing all of the peak output very often - helpful for a newer rider. In terms of features and electronics too, the 390 Duke is much better equipped compared to the 250 Duke. Overall, the 350cc Duke is a machine that you will be able to enjoy for a longer time as you progress as a rider.
I own a Harley X440, which is a beautiful bike but falls short on some areas such as braking performance, tyre grip and front suspension performance. I want to keep the bike while adding another bike to my garage, which will have a distinct character from the Harley and offer better performance in the areas where the Harley falls short. What can be my options in the budget of ₹5L?
Since you already have a relaxed bike in the garage with your X440, we'd recommend you look at something sporty - specifically, the KTM 390 Duke R and Aprilia Tuono 457. The 390 Duke R is a proven product, and if you want a thrilling machine with good cycle parts, it doesn't get much better than the 390 at this price point. Of course, you'll have to deal with some amount of vibrations and the fact that the Duke is quite a cramped machine for taller riders. The Tuono 457 offers a more polished riding experience thanks to its twin-cylinder engine, which is one of the biggest reasons to buy one. It is smooth at almost any rpms, makes a great sound and has plenty of punch almost everywhere. Its handling is also sublime, but it does come at the cost of a stiff ride over broken roads. There's also the fact that the Aprilia 457cc engine doesn't have a stellar reputation for reliability, and the company's sales and service network is quite small. Aprilia's service is also expensive and not always friction-free. The Duke is definitely the safer buy of the two, although if your nearest Aprilia dealer can give you some reassurances on the ownership front, the Tuono 457 is a machine that will keep you happy for a long time to come.
