I replaced my KE21 backplate with the Dynamite pull start back plate eliminator @ $12.99 and fits perfect. The screw holes almost aligned perfectly. If you want to save a few bucks get the Dynamite.

Fits all Force based engines too! Instead of the hard to find 2109

Jarrod CaroonVerified ownerMay 21, 2025on Kyosho Nitro Engine Back Plate (KE21SP/KE25SP2)

Bolted right up to the KE21 engine in my MP10 Readyset. No issues, and makes for a cleaner looking setup, too.

What reviewers say

Three reviewers rate this back plate 5/5 and report that it fits the KE21 and KE25 series engines without issue. One reviewer used it in an MP10 Readyset and found it bolted up cleanly, giving a tidier appearance. Another reports it also fits Force-based engines and serves as a replacement for a hard-to-find part. One reviewer notes that a third-party pull-start back plate eliminator from another brand fitted similarly and was a cheaper alternative. Reviews are few and all positive, so the evidence base is limited.

  • + Fits KE21 and KE25 engines
