I' d question anybody who believes Yamaha would jeopardize their stellar reputation to 'cheap out' on the launch of any new model. Most of the replacement options will come as a complete rear set, not individual pieces.
There are several reputable companies making rear sets for the R3, and several vendors to purchase from who specialize in modifying the R3. Norton Motorsports is a business sponsor for this Forum's site and has been tweaking the R3 since its introduction in 2015. They offer great technical support, both on this Forum and through their customer service.
Most of these quality after-market rear sets are well made, lighter, and stronger than Yamaha OEM parts. But, none are as affordable.
Like most 'upgrades'.. you normally get what you pay for.
