What size pistons are in the R1 caliper?
The Yamaha R1 motorcycle is known for its high-performance braking system, which includes a set of powerful calipers. The size of the pistons in these calipers is an important factor that contributes to the bike's exceptional braking capabilities. According to the information available, the R1 caliper uses 4-piston calipers with 30mm pistons.
Understanding the R1 Caliper Piston Size
The Yamaha R1 is equipped with a high-performance braking system that utilizes radial-mount calipers. These calipers feature four individual pistons that apply force to the brake pads, which in turn press against the brake discs to slow down the motorcycle.
The size of these pistons is a crucial factor in determining the overall braking power of the system. Larger pistons allow for greater clamping force to be applied to the brake pads, resulting in more effective braking. The R1 calipers use 30mm pistons, which is a relatively large size for a sportbike of this caliber.
The Benefits of the R1's Braking System
- Powerful Braking: The 30mm pistons in the R1 calipers provide a significant amount of clamping force, allowing for strong, consistent braking performance even under heavy use.
- Fade Resistance: The large piston size helps to dissipate heat more effectively, reducing the risk of brake fade during extended periods of hard braking.
- Precise Control: The four-piston design of the R1 calipers provides excellent modulation and feel, allowing the rider to precisely control the braking force.
- Improved Safety: The R1's powerful braking system contributes to the bike's overall safety by providing the rider with reliable, consistent stopping power in a variety of riding conditions.
The combination of the 30mm pistons and the radial-mount caliper design is a key factor in the Yamaha R1's reputation for exceptional braking performance, making it a popular choice among sportbike enthusiasts and racers alike.
What cylinder is a R1?
inline 4 cylinder
What brakes do Hellcats have?
Standard on the Dodge Challenger SRT® Hellcat Widebody and SRT Hellcat Redeye Widebody are 390-mm (15.4-inch) Brembo two-piece rotors with six-piston calipers.
What size are piston calipers?
Measure the Hollow Part of the Piston
| Piston Size (mm) | Piston Inner Diameter (mm) | Dust Boot Diameter (mm) |

What are the standard sizes of pistons?
Piston sizes
The industry offers bore sizes of 0.020, 0.030, 0.040, and 0.060 inch. A standard bore is the dimension the engine was originally made to. If the cylinder is worn or damaged, it will first need to be overbored to a dimension and then finished honed to the final size to use a new piston.
How do I know what pistons I have?
If you're lucky enough that the pistons were manufactured within the last 8 years or so they will be identified by laser markings under the pin boss. A custom piston will have a 6 digit job number while a shelf part will have both a job number AND the part number laser engraved on it.
How to tell if you have 4 piston or 6 piston brakes?
If you count the arches, you can usually tell how many pistons are in the caliper.
What size pistons are in the rb25?
RB25 Standard Stroke Pistons
| Part Number | Bore | Pin Diameter |
|---|---|---|
| NIT-CP-RB2520 | 86.5MM/+0.020" | 0.827" |
| NIT-CP-RB2540 | 87MM/+0.040" | 0.827" |
Is R6 faster than R1?
This larger engine size results in more horsepower and torque, allowing the R1 to achieve higher top speeds compared to the R6.
How do I know what size piston I have?
This can be done by using a bore gauge to find the diameter or by reading the owner's manual to find the bore specifications. Ultimately, the bore should be measured for the best possible results. After the diameter is known, then you can pick which size piston will work best in your cylinder.
