Sorry was meant to say ive had it from nearly new, it was owned by suzuki themselves because it was an exhibition bike when they first launched it, had 400 miles on it when i got it in may last year and only got a 6 month warranty from dealer, it would sit comfortably at 75 with a little bit more room to play on throttle i always just used to keep it at 70 so i wasnt thrashing it all the time. Thanks Paul

Hi everyone, I have a suzuki gsx s125. Ive had it a year from new ive done 3,500 miles, the past 3-4weeks my top speed on a flat has went from 75-78mph to 60-62mph im not exactly clued up on motorbikes so was wondering if anybody knows what could cause loss of power?? Bike was serviced in febuary and had no power issues until 3-4weeks ago where it seems to struggle to get to 60 ive had air filter changed hoping that was the issue. Any advice would be appreciated Thanks Paul
