Message: [QUOTE="JST122, post: 1066239, member: 65931"] You are always going to have a lot more shift points on the track with a 2 stroke compared to a 4 stroke, thats just the nature of the beast. When I ride my KX 250 on the majority of tracks I use 1st through 4th gear and am continually shifting between these gears as necessary to maintain peak power. The tracks with long fast straights Ill get 5th where as on my 450 I ride just about all of the local tracks in 2nd and 3rd gear and will only get 4th on the long straights. The result is a lot less shift points to maintain the speed and power to clear the obstacles. This aspect makes the 450 easier to ride fast. In your case on a 125 the shifting is going to be even more frequent than the 250 2 strokes just becase as oldfrt said above you need to keep the 125 in the upper rev range to maintain effective power on the track. If your goal is to shift less and maintain power and speed then a 4 stroke will do that for you but you have to consider all of the other tradeoffs associated with switching from the 2 stroke to the 4 stroke like, maintenance schedules/costs and weight. In my opinion if you are just riding for fun and not competing you dont need the 4 stroke but if your goal is to be more competitive in the small bore class and turn quicker laps with less shifting you dont have many other options.
