BLP9 - Group 9-12V Lithium Battery - Powersport Li-ion Phosphate - 120A for Motorcycles, ATV/UTV, Snow Mobiles, Personal Watercrafts, Scooters and Jet Skis - 5.91″ x 3.43″ x 4.13″

I bought this Bosch Lithium Battery BLP-14Battery for my 2013 Aprilia Tuono 1000 V4 engine. I replaced my 2-year-old Energizer AGM Battery was giving me a hard time starting after Refueling. I read many reviews where people were saying Lithium Battery turns the engine over faster. I also notice the same thing. My Aprilia V4 never started so fast before, and I have had this bike for over 2 years now. This battery seems to be 25% of the traditional battery weight. I only had this battery in my bike for one week now. Time will tell how long it will last, so far I am very happy with it. We don't have to worry about cold Lithium start as i live in South Florida. Our summer is 100°F and Winter is 60°F if it's a cold day. Don't forget to buy Lithim Compatible Battery Tender Non Non-Lithium Battery Tender will ruin your battery. I did a lot of Research and didn't know what to expect, but i am glad i bought this battery.

Seems to be good replacement battery. Used to replace a "heavy" AGM battery in my CanAm Spyder. Fits great after using the adapting spacers. Appears to be a good value. Seems to crank the engine right over, starting easily.

You have to make this battery fit in your motorcycle. It is much smaller and lighter than your original battery, and it comes with lego-like blocks to help it fit in your battery box. Wouldn't work in my bike, even though the battery was cataloged as the correct model. These lithium batteries are light and they are small, but they are not plug 'n' play. I returned mine to Whole Foods and bought a normal maintenance-free battery.

This BLP14 is a step beyond the level required for my bike; the BLP9 is sufficient according to the Bosch match for my bike's Yuasa battery. However it is still radically lighter, saving about four pounds by switching. Between the price being about the same as buying a lead battery and the weight and performance, I highly recommend this unit. One nit you should be aware of: the battery terminals do not hold the rectangular M8 nut semi-captive the way the Yuasa terminals do. So I recommend care and either a small rubber band or some electrical tape to avoid losing the nut during installation.

Great replacement for my 1000sx

I bought the Bosch BLP14 battery for my Ibex 450 motorcycle, primarily for the weight savings. It arrived in good shape with the indicated multitude of spacers, and the terminal bolts and nuts. As usual I had to put little pads under the nuts to locate them in place and raise them up to where the bolts would easily engage them - why we still have to do this after decades of this poor design I don't know. Otherwise, it went in easily and the bike started and runs fine. Time will tell how it holds up, but I suspect this battery from a company like Bosch should do well. Now, regarding the battery dimensions. The Amazon description for this BLP14 variously shows it as "3.43"D x 5.91"W x 5.63"H" and "3.43"D x 5.91"W x 3.63"H". The Bosch website was no help on this mystery, but I suspected it was the smaller height for this Class 14 battery. I measured it and in fact the actual height is 3.63" so it should fit as a replacement for batteries such as a Yuasa YTZ14-BS. The 5.63" measurement would reflect the use of some of the included spacers to raise the battery height, if needed. Hope that helps!

Cranks the motor better than stock. Much lighter than stock battery and notice it during daily driving. Ingenious mounting blocks that make the battery fit perfectly. So far, so good.

Works great on my 21 Road glide
