i am not sure, but 1989 model is somewhat special, jis mechanic kay pas jao, he immediately makes an offer, its the heaviest among all yamahas, n has the most beautiful road grip among all the yamaha i hav ever driven,,,, its acceleration is greater than even 125, uptil 1st 3 gears, it beats the **** out of 125, but 125 has greater rpm in 4th gear, so it lacks behind due to 25cc difference.
