Suzuki has recently unveiled their 2015 off-road range, which includes the DR200S you see here.
The DR200S uses a 199cc air-cooled engine which should provide enough punch for town riding without being too intimidating on the trails.
Unfortunately, due to Europe's strict emissions laws the little DR won't be coming to the UK. At the moment it's a US-only model.
If you're not in the US and are in the market for a bike similar to the little DR, bikes like the Honda CRF250L and Kawasaki KLX250 are both brilliant alternatives.
