Don't worry homie, I got it done by a mechanic who's been working with RXs forever.
I paid 85k for the bike because it was absolutely perfect and didn't even have a single scratch on it. I've been riding it for close to six months and haven't had any problems at all with it. If it's an RX100 in just average condition then you can probably sell it for 50-60k on Facebook Marketplace.
Yes I touch 90 at least once everyday on my way to college. It doesn't struggle at all and I think if I keep at it I'll probably reach speeds of upto 110kmph. I don't think the brakes can slow me down fast enough if something comes in my way though. (I didn't upgrade to disk brakes)
