Hello, I have such a question. With my Derbi Senda xtream 50 you can’t drive slowly ^^ It’s tuned, sports exhaust, other translation certainly also, carburetor etc.. It makes a lot of fun and drives so about 110, which is “super” BUT.. the part is so hungry that slow driving doesn’t decide ^^ So: 1. gear: to drive, and about 15 kmh 2. 10-30kmh 3. gear 45-60 kmh 4. 55-80 … the problem is between the 2nd and 3rd gear, it’s almost not possible h constant 40 kmh to drive, because the 3rd course still has too little power, the second one however already at 7000 rpm, and crazy according to the performance optimum is so about 5500 upm D.h, sometimes when I normally drive in the 3rd course 50, and then it goes uphill he even loses speed, although the mountain is super flat. for the 2nd course is 50 but too fast.. well. someone nen tip, how to solve this complicated? or is that normal so? bought the mop so MfG
