Yes, it’s hard to tell from the angle of the pics. I dug around on some Italian website here is one things I found via google translate. Sounds like TJ said not a lot of changes mostly cosmetic
“These are the main technical innovations 2019:
Chassis for the OK category:
•Same frame in the geometries but with technical improvements regarding the components.
•Steering wheel with HGS covering for better precision and driving comfort, supplied with an inclined hub.
•Integral floor plate to grant a better aerodynamics.
•Front spoiler M7 with low aerodynamic coefficient, provided as standard.
•New bodyworks graphics
RACER 401R and 801R KRYPTON
Both of our top models have been further evolved with a specialization work arising from the adoption of new equipment used on the production line. The bodies of both models are the developments in the steering column support attacks and attacking the front bumper.
OK models come with a change to the central flange, forged according to a new design to best accommodate the exhaust of engines and OKJ OK.
The other components which have focused the attention of our technical department concerning the register of the throttle cable and the hub holder (with two screws).
Bring new products, always by mechanical techniques best performance, it is the goal pursued by OTK that among the interesting news offers an advanced platform, whose thickness is 1.5 mm, and the chain guard support, one-piece and made of a new material , lighter.
The overall upgrade on the components and the constructive elements mentioned above, allowed to marry always be a factor not easily visible, but of great substance, the weight.
Today RACER 401R and the 801R KRYPTON are lighter than their predecessors, and the drivers have the obvious advantage of being able to handle even better weight distribution.
The continuous evolution of each component could not but affect the braking system, now equipped with BSD pliers, forged in one piece and able to guarantee greater rigidity, strength and stability of yield”
