Information on product safety
Report error
Grey cast iron cylinder for clearly optimised driving performance, with unlimited durability.
This is almost a blanket recommendation for all those who want to make their scooter faster without a lot of effort.
The DR differs in optimised control times and, above all, larger channel widths, especially the overflow valve. The DR philosophy is to give the cylinders a wide speed band with lots of torque from the lower speed range. The 70cc version is particularly impressive.
The price/performance ratio is very good and the richer torque is simply fun.
