In general terms, softer, stickier tires will make the bike feel more planted and controllable, but wear faster. More durable tires last longer, but may slip a bit in hard cornering. This doesn’t mean the harder tires are less safe — it’s more a matter of choice and matching the tire to the bike and the rider’s needs.
It’s almost universal among new bike owners that the stock tires are less than perfect. But they are also the cheapest tires you’ll ever have — since you already own them. So unless you are immediately finding that you are pushing the bike past the limits of the OEM tires, I’d advise riding them to their wear markers and then upgrading to one of the models favored on your favorite 650R site. But be forewarned that it’s rare for even the experts to agree on the best replacement.
