I'm a newbie to TW's, I've had various bikes through my life but not a fat wheeled DP. So I'm looking at a 1987 TW200 with 1600 miles, it's all original including the tires. It has been stored indoors and run every year but obviously not much. Mature owner (older guy). The thing is near new condition. Is there anything I should look for with this vintage? Are parts available? thanks in advance
