It's been a few years since owning my first bike, a 88 RM 250. Came across an 87 dr 125 that needed work for cheap so I bit. It needed some odds and ends and i got it running. Found a parts bike same year for cheap so I got that. Went to switch the brake calipers over and discovered something different. Apparently somebody jacked this bike up with larger forks and rear shock. Never had the 2 bikes close together to notice. Is this a common practice?
