Modern sportbike design emphasizes reducing weight, especially up high in the chassis. The OTT crew took five pounds off the OTT project GSX-R by replacing the standard lead-acid battery with a Full Spectrum lithium battery as used by various AMA Pro racing teams and available through dealers everywhere. This video is sponsored by SportbikeWrench.com, which also has batteries in stock. Be sure to check out other Roadracing World feature videos.
