Suntour Fork Service/Upgrade

79stef · May 15, 2021

My current bike refresh/build has the fairly budget Suntour SR MG80 (circa '99-'00) forks fitted. I am struggling to find much info on them.
They're currently set to their stiffest setting (I weigh 100kg) but I'd like to service them for piece of mind. When doing this, is there a way to adjust them more to my weight (stiffen them)? Im new to suspension forks on mtbs and only know that when I do this on my motorbike, I can add stiffer springs, more viscous oil etc to tailor the setting to me.
Any info, tips, tricks, appreciated!

Suntour forks of that era were not great. If budget allows I'd be looking at replacing them with something better. They will work, perform better and be lighter and more robust.

Thanks ishaw, that is definitely my overall plan. I was keen to bring the whole bike back to its former glory before riding it a few times, getting a feel for it and then changing out what I need to.
Do you have any recommendations on replacements (specific Judy, Bombers around 1999-2000?)

Depends on whether you are fussed about period correctness or not. Marz seem to be bullet proof retro forks. Assume you are after v brake ones, so more modern fork options are limited but not impossible, such as reba, fox manitou for example.

Thanks, forgot to mention, it's got Magura HS11's fitted. Yes, I'd ideally prefer period correct but realise that limits me somewhat
