User Reviews of Trident 660

Fast When You Want, Calm When You Need!

The 200 km/h top speed may grab everyone's attention, but what impressed me most was how calm the bike felt while riding. It never felt like it was trying too hard. On another day, I crossed a road filled with broken patches and loose gravel. The tubeless tyres handled it without making the ride stressful. That's what I enjoy most about the Trident 660. It has the performance to excite you, but it also makes everyday rides feel simple and comfortable.

They've Become My Favourite Riding Companions!

The turn by turn navigation has saved me more than once when I've taken a wrong turn during my daily commute. Instead of stopping to check my phone, I simply follow the route and keep moving. On weekends, it's the cruise control that steals the show. Holding a steady speed on long highway stretches makes the ride feel much less tiring. Somewhere between weekday traffic and weekend escapes, these two features became part of the way I ride without me even noticing.
