Improved feel and braking performance

About quality and texture - The P4 right brake caliper from Brembo is made from cast aluminium with a black anodized surface finish and includes brake pads, the quality from the overall fit and finish is perfect.About the feeling of use - The P4 right brake caliper is initially overwhelming to look at on the minimoto with it's massive physical appearance but soon becomes part of the Monkey 125 with it's black finish that matches the original styling, not to mention the improved feel and braking performance with it's larger diameter pistons and higher quality brake pads.Products to buy together - The Honda Monkey 125 is an inexpensive motorcycle with a lot of low quality parts from the factory, so the purchasing of other high quality parts like this P4 right brake caliper from Brembo would be perfect but the essential product to purchase to complete the installation is a front brake support bracket to allow for the meshing together of the Brembo brake caliper and the Honda lower fork leg.Difficulty of installation - The installation of the P4 right brake caliper is a intermediate task that took 0.7 of an hour to complete. Some mechanical aptitude and the use of basic hand tools is what is required to secure the P4 right brake caliper to the bracket and bleed the brake caliper.Cost performance and comparison with other products - I find the cost of all the products Brembo sell to be higher then what most other companies sell their products for and the P4 right brake caliper is no different, but this is due to the high quality materials used and the consistent high quality finish of their products.About shipping and packaging - With there being no significant cost difference between sea freight and EMS for the P4 right brake caliper, I chose EMS for an earlier arrival dates. The part was extremely well protected while being covered in bubble wrap and surrounded with air pillows in a sturdy cardboard box.Any concerns, cautions, or advice when purchasing - Webike Japan is the first place I look to for all my motorcycle needs. From service parts to performance products and even motorcycle gear and apparel, Webike always seem to satisfy my needs in regards to availability and pricing.

Good!

Replaced from 2013XL883NOEMCaliper.

The OEM Caliper was rough and could not adjust the Breaking in detail, but with brembo 4 pod + mesh hose, subtle Breaking is now possible. 。
♪ It's fun to run ♪

Expected

This is a replacement for an OEM Caliper that has been used for over 60,000 km.
I replaced it with a Large one for no particular reason, just because it was getting old and I thought it was time to change it, but I'm glad I did. I'm glad I bought it because it has improved controllability very much!

P4-40C Brake Caliper P4 30/34 40mmBlack, Left

The position and angle of the piping outlet is different from OEM, so you may need to change the hose in some cases. I originally plumbed 1 pc down from the Nisshin radimas.:Pair (for Left and Right) Left is a BridgeHose with Straight connection. This should be the simplest configuration.
The braking force of the pad is more relaxed than that of the OEM Caliper&DaytonaHyper pad, and the impression is that it is not effective. It is not Caliper's characteristic but Pad's characteristic, so it is good to change it. (DAYTONAHyper pad is also a loose characteristic that works well.) I think it has something to do with that. I think this is also related to the fact that the Rajmus grips more than the Horizontal Type.
The quality is 100 times better than KATANAOEMTokico, and since it costs a lot of gold to OH the OEM, the Brembo cast with pad is a very cost-effective option. The appearance is also good with matte black and glossy logo parenthesis, and if the BridgeBolt is also black, no complaints.
Pad pin is lightly press-fitted and not easy to work with, so I intend to change it.
