Guys, Dont get yourself into trouble... please undestand this first before you buy the KOSO digital meters.
there are different models with different prices.

RX-1 / RX-1NR   :  This is the BASIC model, this one does NOT have the Speedo. it ONLY has  RPM, TEMP & FUEL  Price is RM 300 - RM380

RX-1N :  This is the FULL model, got Speedo, RPM, Temp, Fuel, etc..etc & etc... complete details.  Price is RM720 - RM800

RX-2   :  This is also the FULL Model, function same as RX-1N but different only in design. Price is UNKNOWN

RX-2N :  This is the FULL Model, same as RX-1N, but different only in design. Price is around RM750 - RM900

RX-2NR  :  This is also the BASIC Model, limited features but ONLY DESIGN are same as RX-2N. Price is range from RM350 - 450

Price depends on where you buy and who sells. IF you buy any of the items. Please make sure you check that all the sensors and relevant brackets for the sensors and the meter are also included. these are DIGITAL meters. they dont use mechanical cables. they use electronic sensors. be careful. there were a lot of items in the package box. make sure you check all of them before buy. or else, you'll find it hard to install.
basically, below are stuff you should expect from an RX-1N Package.


its complicated. if you dont know how to install them, please ask the shop to do so and always observe the installation.
By the way, below are the difference between them.
