Let me start off by saying you must upgrade your seat, it's the first thing you need to do.
Either buy this 'Deluxe Float Seat' or the 'Float Seat' they're almost identical.
I tried the original seat again on my sisters Sur recently and the difference is night and day. You'll never want to go back to using the original seat. Even for 5 minutes, take my word for it.
This new seat is much more comfortable but if you've already experienced chafing or have ridden a few times per week for at least 1-2+ hours a day then you're probably feeling the burn as soon as you get on any seat or lay down for that matter. It takes time to heal... this seat helps avoid that because it has cushion and it's more "forgiving" but it's still a possibility which mostly depends on what pants you're wearing, how rough the road or terrain is (while sitting, not using pegs to stand), how long you're riding, the rear suspension settings (the spring under the seat which you can adjust: bouncier or firm)
Regardless of chafing, it's still a better seat overall.

Bumps on the road make chafing worse because it causes your body to bounc around & rubs with your pants & seat so street riders be advised that if you ride with the Super Moto tires and go on rough roads with lots of bumps and uneven pavement it'll eventually take it's toll.
Depending on what you're wearing, and everything else I've mentioned you can make your ride more comfortable.
Also fyi, know that the stock dirt bike tires go over bumps and really bad roads like butter but they're not the best for turning or braking, you can get Shinko 244 (dual sport) tires to improve braking stability but one more reason I prefer not to use them is because of the height.

I also advise wearing something comfortable for long rides to ease the friction as much as possible. (I'm not into cycling gear but that's probably one solution)

Luna Cycle has the best customer service, I recently made some upgrades and purchased a new battery, the technical support was outstanding.

I love this seat it’s so comfortable

These are perfect for riding in the streets way more comfortable than the stock

Works awesome

Quality handle bars, great price

this bash plate is a must!

Great 1st experience with luna cycle. Order was quick and adapter worked perfectly.

Absolutely love my Apollo. Will definitely be purchasing another Luna Cycle product.

Means to an end. The brace rattles, but I fixed that with a little tape on the ends. they flex a lot still, but I have not experienced a failure in +500 miles

So far I am happy with the performance, they fade later than the stock rotors for sure. I have only used with the ho3c pads.

I was really happy with the service I received from luna Reilly fast postage and awesome communication thanks heaps for getting me back on the road I am lost without my bike

I haven’t used it just yet, the adapter I used with it blew a fuse, ( Europe ) all other electronic devices are 220vac, this came in plugged for 110. Just haven’t gotten a new adapter yet, I borrowed one to confirm the charger was ok, not a normal item for me.

Love it it gives the bike the look it should have .

Extremely happy with my Bafang mid drive ebike kit. Installation was a breeze. It is almost as if this kit was made for my bike specifically. Surly pugsley fat bike

The reinforcement is a must have, kickstand will need to be shortened with this kit

Gives a little kick! Works great, i wanna try the 54,but you guys are sold out😩 other than that.. Highly recommend getting a bigger sprocket for your SURRON!

This bike is awesome! It arrived very well crated & packed. A Really hi quality bike, this bike is super fun to ride.
The range is really good on this bike, and the throttle control is very smooth. I'm very happy with this purchase.

Only way to get my chain line close! And it looks really good!

Great throttle, its a huge improvement from the thumb throttle that came on the bike!
