2018 Ducati Monster 821 vs Triumph Street Triple RS: Spec comparison

By autoX Editorial | on April 30, 2018

The latest-generation Triumph Street Triple RS has already proved itself to be a brilliantly all-rounded motorcycle. It isn’t just a great everyday superbike, but also a fun track tool. However, Ducati is set to challenge Triumph’s supremacy with the thoroughly updated Monster 821. Here is how these two European street fighters compare on paper.

Physical overview

Both these motorcycles look worlds apart. For its latest gen model, the Street Triple sports an evolution of its signature bug-eye design, which still remains a love-it-or-hate-it design. The Monster 821, for the 2018 model year, celebrates the classic Monster 900’s silver jubilee by incorporating some elements from the latter. As a result, it retains that characteristic Monster look that we’re so familiar with.

Wheelbase 1,480mm 1,410mm
Weight (dry) 195kg 166kg
Seat height 785mm - 810mm (adjustable) 825mm

The biggest strength of the Street Triple is its weight, or rather the lack of it. At 166kg (dry), the Street Triple RS manages to undercut the Monster 821 by 29kg indeed a significant figure by motorcycle standards. The Triumph is also the more compact bike of the two, however, we cannot say exactly to what extent because Ducati has not released official figures of the 821’s length, width and height. What we do know is that the Triumph features a smaller wheelbase. However, the Ducati will be friendlier for short riders, as its saddle height is lower and adjustable.

Engine and gearbox

The Monster 821 is powered by a 821cc, L-twin engine that pumps 107bhp of power and 86Nm of peak torque. This fuel injected motor is water-cooled as well. The Triumph on the other hand sports an extra cylinder on its 765cc liquid-cooled motor that outclasses the Ducati with its 121bhp. However, its torque output at 77Nm remains lesser of the two. Both bikes feature a 6-speed gearbox with slipper clutch as standard.

Price

The Triumph Street Triple RS is priced at Rs. 11.13 lakh (ex-showroom, pan-India). The Monster is 821 will set you back by Rs 9.51 lakh, which is indeed an attractive price when you compare it to the Triumph. Also, the 821 is only about ~Rs 1.25 lakh dearer to the smaller Monster 797 - but for that extra money you get a lot more power and added equipment.
