There is an easy and quick way to lighten your bike, lower its center of gravity, and marginally improve its dynamic performance for $200 or less: the starter battery.

Lead-acid, absorbed gas mat, and gel batteries have been around for years now, and while they provide cheap, reliable, and robust performance, they are obtrusively heavy and large.

In terms of packaging and placement, most bikes have them mounted high and away from the center of gravity; basically, it’s like carrying around a brick at arm’s length all day.







Luckily, the market for starter batteries has been moving in the direction of new battery technologies with the latest iterations utilizing lithium iron phosphate chemistries.

These batteries are not plagued with the same issues that lithium ion batteries faced (read: exploding when cycled improperly), and are more environmentally friendly and theoretically last longer than the equivalent lead-acid or AGM battery.

We had two companies send us their most popular models for testing and we came away impressed with the weight savings, performance, and overall value that they had to offer.













For 2010, Yamaha has made some minor tweaks to the YZF-R6 that help bolster its midrange performance. By adding a 100mm longer exhaust pipe, remapping the the R6’s ECU, tweaking the variable length intake stacks, and revising the airbox, Yamaha has allegedly found more grunt down low, although the company hasn’t released exactly how much grunt they found with these improvement.

Continue reading to see the rest of the changes to the R6 for 2010, but to warn you in advance, you won’t see a cross-plane crankshaft listed after the jump.
