TYKOOL LFP4L-BS-STD Lithium Battery, Replaces YTX4L-BS, 140CCA 2.8Ah Fits for Motorcycle ATV Scooter Dirt Bike, Compatible with Honda CRF50F CRF110F Yamaha TTR125, Digital Readout, Polarity [- +]
The TYKOOL LFP4L-BS-BS drops right into the CRF50F's small battery tray as a direct replacement for the stock YTX4L-BS, so no bracket modifications needed. At 140CCA it delivers more than enough cold-cranking power for the 49cc engine, and the built-in digital readout takes the guesswork out of checking charge state. Lithium chemistry also means significantly less weight than the OEM lead-acid unit. Caveat: the higher upfront cost is hard to justify if this bike mostly sits in the garage between occasional weekend rides.
