Aprilia RX125 SuMo conversion
Hello, I have the 2025 Aprilia RX125 and was wondering if there is anyone familiar with converting it to a supermoto? I know that both the RX and the SX model share *almost* the same platform but i am not sure if there are any difficulties or not-so-obvious things to keep in mind. My biggest concerns are wheels (service book says that they're 17x2.50 front and 17x3.50 inch rear) - should i aim for getting OEM Aprilia SX125 rims or are there any sets that will fit (something like smpro) and is not OEM. Additionaly stuff like rear sprocket and brake pads obviously and if there are any difficult mechanical changes that need to be done to fit larger wheels despite the platform being very similar.
This would be my first attempt at a SuMo conversion so any extra tips will be appreciated - my biggest fear is probably ordering parts that just won't fit (the swap on Aprilia isn't as common, most likely because SX125 exists). I couldn't find too much information online about converting the RX so i'm looking for someone with first hand experience.
I will appreciate all the tips and knowledge you're willing to share with me, thanks!!!
