First Look: 2020 JGRMX Suzuki Engine Packages 3

Check out what JGRMX has in store for the 2019 and 2020 RM-Z250 and RM-Z450. There are two different engine packages to choose from as well as other protection and suspension parts.


On the heals of Suzuki announcing their 2020 bikes, with no changes other than colors in the graphics, JGRMX has some much needed news for yellow bike fans. At the Fox National in the JGRMX/Yoshimura/Suzuki Factory Racing Team pits, it was announced that JGRMX will be offering Stage 1 and Stage 2 Engine Packages along with some individual engine parts for the '19-'20 RM-Z250 and '18-'20 RM-Z450. 

Stage 1 includes a piston and a GET ECU that is preprogramed with the maps that the JGR team uses. There is also a two-way map selector switch for the handlebar. Stage 2 is a piston, GET ECU, map switch selector, and fully-assembled head, including valve train, race cams, and custom team porting. The heads are stock OEM Suzuki units straight from Japan, then the same engine dudes that are building Martin's, Hill's, and Peters' bikes build these for the customer.

Fully ported head with race cams. The valves are stock to keep the reliability factor high.


Pistons are also available separately.

The GET ECU is a powerful tuning tool, and a must for race bikes.

Carbon protection bits and adjustable linkages are also available from JGRMX.
