KTM 790 Duke Vs Triumph Street Triple S: Spec Comparison

With a nickname like the Scalpel, the KTM 790 Duke promises to be one of the hottest bikes to arrive on our shores this year. Admittedly, it will be a limited run model and will cost a bit more than what we earlier thought of. However, there is no denying that the 790 Duke is going to be a fun bike to ride. In this hotly contested middleweight segment, the Triumph Street Triple is the bike to beat. Given that the pricing of the 790 Duke is expected to be near the S variant, here’s how the two bikes stack up on paper.

Engine & Electronics:

The 790 Duke is less powerful and packs one cylinder less, but KTM has tuned the new 799cc LC8 motor to be as punchy as a big-bore single. No wonder it makes more torque at lower revs than the 765cc triple. Where the 790 triumphs over the Street Triple S is in the electronics package. Plus with goodies like wheelie control, Supermoto mode, cornering ABS and a bi-directional quickshifter are not even available on the top-of-the-line Street Triple RS.

Maxxis Supermaxx ST tyres

Front: 120/70 - ZR17

Rear: 180/55 - ZR17

Pirelli Diablo Rosso II tyres

Both middleweight nakeds are on par when it comes to the components found. Where the 790 Duke might have a small edge is with its J Juan radial calipers while the Street Triple S has to make do with  smaller Nissin twin-piston calipers. However, we believe the Triumph's Pirelli Diablo Rosso II tyres will be grippier than the KTM's Maxxis Supermaxx ST tyres as the latter compound is more of a touring-biased tyre.

One would think that the KTM is the more compact and lighter of the two motorcycles. However, the specs reveal otherwise. The Street Triple S is lighter by 3kg, has a 65mm smaller wheelbase and has a more accessible seat height. And the extra 3.4 litres of fuel aboard the Street Triple S means you can stretch your riding stint for a longer duration.

Rs 9.19 lakh

We had earlier expected KTM India to be bang on with the pricing like it has done in the past with the 390 Duke. But rumours suggest that the 790 Duke will be a pricey affair as it is likely to arrive via the CBU route. Hence, we believe it could be priced around the Rs 8.5 lakh mark. While that may seem like a lot for a KTM, it will still be nearly half a lakh cheaper than the Triumph offering.
