Fuel efficiency and power-up parts "Geki Quantum Series" - The ultimate model now features a new ferrite core!! Experience performance like a race car! ★ User Reviews (excerpted due to length) Today, I finished using the Ultimate on my light truck and wrote my impressions. Then, I temporarily installed it on my motorcycle and rode it, and I was amazed by the incredible performance. The engine revved up with a burst of torque, as if something had cleared away, and even at high speeds, cornering was completely worry-free. It became so easy to control that I almost felt like I had become a better driver. It was not comparable to Quantum Z2. My motorcycle became so fast and fun that I decided to purchase the Ultimate without hesitation. The difference was much clearer on the motorcycle than on the light truck. Since there is no space under the motorcycle seat, I will install it outside as shown in the photo. The position in the photo is a temporary installation and may interfere with pedal operation, so I will install it in another location. #Battery #Tuning
