What Is It Like?

Why The Terrain?

So having owned the bike for around two months I can easily say I am well impressed with the build quality of this bike from the crash bars to the luggage cases as standard. The parts warranty and AA cover as standard pushed me towards buying this bike.

Ride Quality

So after getting used to the bike I ventured further and further on it. I enjoy the upright position of the ride and the smooth gear change.

It really doesn't look or sound like a standard 125 cc. For its size it feels light and easy to handle on any road surface.

The dual braking system certainly feels different to other bikes I have ridden and I have been riding mine 30 miles to work on the A19.

If I'm honest it keeps up with the traffic with the wind behind you but once you hit a slight bank it starts to slowly reduce speed making you knock it down to 4th to keep the speed going.

Pros

  • Great build quality
  • Good fuel injection system
  • Extra luggage space
  • Smooth gearing
  • Digital display
  • Good braking system
  • Nice sounding
  • Good all round bike

Cons

Pedal vibration - after riding for around an hour I noticed that when I dismount the bike my hands and feet were still vibrating off the ride.

I have bought a handlebar strengthening bar to see if it will stop the vibration in my hands and I have also purchased some hand guards to prevent anything hitting my hands.

Summary

It's a good all round bike. I would fully recommend it for long distances on and off the beaten track. I will be upgrading to the T380 in a year or two.

The Second Opinion

Sinnis Terrain

My Sinnis Terrain AKA "The Tank"

It's a perfect budget bike, a great starter bike and all round amazing. It handles like a dream and can definitely take a hit! I've unfortunately had mine stolen and involved in a couple of accidents but it's got back up and turned right back on, hence the name tank!

Any Downsides?

It does lack power for the size but doesn't fail to get you from A to B.

Mods

I would recommend to change the chain / sprockets to a DiD chain / sprocket set and the headlight to an LED bulb.

To Sum Up

I would definitely recommend the Terrain for anyone just starting out or who just wants a smaller engine for commuting. It's comfortable and stable.
