Suzuki RM125 – Sold

I got chatting with some guys at work that have dirt bikes and started getting the bug again.  Back in the UK my favourite bike was a 90 odd Suzuki RM125, I didn’t want to spend much money so when I saw this 1992 version going cheap I had to go check it out.  There are some issues with it but I ended up doing a good deal and bringing it home.

RM125AdPic5Looks like it could be fun once it’s running, I’ll work on it over winter ready for next season.

Here’s how it looked after I had fixed up and was ready to sell it.

    Finally built up enough courage to go to a track and try the bike out. The closest track to me is RJ Motorsports who open on Wednesdays for practice. I decided to take the day off work and take the wife with me for moral support. Trying to overcome some hefty anxiety, I found the place ok and got there quite early, there was only one other guy there – perfect. After a quick warm up, I went out but had to come back in after 2 laps, my forearms were hurting badly. Softened off the compression damping on the forks a few clicks and it was much better.
    After another half a dozen laps or so, I noticed that the front mudguard was wobbling, 3 of the 4 mounting screws had come out! Started looking on the truck for a temporary replacement screw so I could keep riding a bit longer and then noticed that the bolt holding the sub frame was also missing! Anxiety was still bad and I was tired so I was quite happy to pack up at that point, I made it out and know what to expect now.
    After fixing the issues, I decided to spend a bit of time tidying up the looks. I always say it’s a dirt bike track, not a fashion show but the previous owner had painted the mudguard and side panels and it had started flaking off making it look nasty. I scraped off the rest of the paint, got replacement screws for the mudguard and sub-frame and finally did a decent patch job on the seat using a bit of old Porsche seat leather since I cannot find a seat cover anywhere. Now it’s ready for round two, but so are the kids so I will have to find something for them to ride as well.
