Tired Of Waiting For The Triumph Thruxton 400 Launch? Check Out This Triumph Speed 400 Modified Into A Cafe Racer

With the clip-on handlebars and other modifications, the bike looks like a proper cafe racer

K-Speed Customs, a Thailand-based bike modification shop, has unveiled their latest build based on a Triumph bike. This time it’s a cafe racer based on the Triumph Speed 400 called the ‘Diabolus Cafe Racer’. This modified Speed 400 looks quite rugged and can easily give the upcoming Triumph Thruxton 400 a run for its money.

The Diabolus Cafe Racer comes with a lot of changes that have transformed the stock Speed 400 from a roadster to a cafe racer. First come the new clip-on handlebars which will change the upright riding posture on the bike to a sportier and more committed stance. 

In terms of design, K-Speed has made a couple of changes. The first of which is a new headlight: this one is a bit sleeker and gives the front section a smaller profile. The instrument console has also been shifted and is now placed below the fuel tank. The fuel tank also gets a tank cover from K-Speed 

Coming to the engine side, the crank case comes with panels that feature a machine finish in matte black. The exhaust is a custom unit from K-Speed and is a smaller one which extends till the bike’s underbelly.

At the rear, the Diabolus Cafe Racer comes with a chopped subframe and tail section giving the bike a smaller profile overall. In terms of underpinnings, the bike hasn’t seen any changes made except the addition of new Pirelli Diablo Rosso 3 tyres. 

All the modifications on the bike have been done using custom parts from K-Speed and customers who are interested in modifying their Speed 400 can buy the parts individually from their official website. The parts can be shipped for zero shipping costs but it will likely attract import duties so it is best to reach out to the custom house for more details. 

Additionally, K-Speed has also listed the Diabolus Cafe Racer on their Japanese website and it comes at a price tag of Rs 10,43,400 which is a massive jump from the Speed 400’s ex-showroom price of Rs 2,34,497. 

If you don’t want to go through all that hassle and just want to get your bike modified with new colours then this showroom in Pune which is offering custom colour options for the Speed 400 and Scrambler 400 X might be what you’re looking for.

Overall the modifications are limited to changing the bike’s appearance, and performance remains unchanged. The Speed 400 is still powered by the same 398.15cc liquid-cooled single-cylinder engine that produces 40PS and 37.5Nm.

Triumph the OG

It's is a 40ps powerful engine with low end torque which gives you city ride comfort and highway cruise. Beyond 80kmph it gives you amazing feeling and achieve upto 140 kmph easily and feeling very comfortable. Maintenance also very normal such as 150cc and 220 segments. In this 2.5 year. I feel very proud of owning this bike.

Best bike for all type of rides

I chose speed 400 for its smooth power delivery stable in high speeds and best suspension and very fun to ride. Its has a very rerto morden looks its power is crazy and at high speeds i feel it is very stable. Positive. Comfortable and confident both in city and highway riding. Refined engine, good handling and good looks. Very fun to ride at high speeds too Negative. Is its mileage I think my bike is new that why i am getting 19. I think if your are traveller or a person who wants to explore new places with bike you can blindly choose this bike you will never regret in your entire life because if you want to ride 500 or 800 or 1000 you will never feel tired

Review as per the user

I choose this bike bcz of the power and for the style. I love the colour the pattern of the design. the height of the bike is best for mine segment and the handle bar is very smooth for those sharp turn. positive but the mileage is quite okay, I feel heating issue limited time not every time this is the negative side if this bike. And the positive side of this bike is this bike is best for city use and also for the touring purpose bcz of this 400 cc engine. yes if anyone want the power then why not the 400 cc is best from the city and touring use. The torque of the bike is fine and powerfull. If anyone don't want hard handling then they can choose speed 400 bcz this bike handling was so smooth.
