What model RM? 130 or 150mm brake?
Yes but the 80 forks are 180mm spaced apart and older 36mm forks are 175mm. As with all Suzuki parts around this era you can assume it will fit, either with no mods or very minor mods. The gap between where the wheel fits might even be the same requiring no mods, but if its different you may need a shorter RHS spacer or maybe an older 76-77 RM/PE one but i think they are same length anyway?. The brake plates might be wider at axle point but i doubt it. if it is and its the 125 hub, then use any 130mm brake plate from any pre 80 36mm RM/PE front end. If its 150mm RM250/400 hub then use any 150mm plate from any pre 80 suzuki with 36mm forks. Slim chance the spokes will need a slight adjustment but doubt it. It will work one way or another because i am doing the same swap with some of my bikes. All this stuff interchanges pretty effortlessly.
