UK46 chest motorcycle clothing should be compared using the garment's own measurements and your intended equipment setup. Replacing a familiar jacket is a good opportunity to reassess its fit rather than copying the old label. The cut, layers and protective components of the new garment all need individual attention.
Use a fresh measurement
Check the relevant chart before choosing the replacement size. RST's men's jacket and one-piece suit guide pairs UK46 with EU56 and XL, but that relationship does not establish the sizing of every manufacturer. REV'IT! directs buyers to the product-specific chart on each product page. Keep your measurements with the model details so you can compare the correct information if you change brands.
Identify what you want to improve
Think about the previous garment in use. Did the sleeves pull back when reaching the bars, did the waist bunch when seated, or was the collar awkward with your helmet? Use those observations to guide a fitting of the new cut. Bring the layers, trousers and gloves you expect to wear, fasten the jacket fully and test normal riding movements. Avoid judging it only by how easily the main zip closes.
Check the protection setup before deciding
Establish which protectors are included and which require separate purchase. Confirm the specified insert size and compatibility, then assess the garment with the intended setup in place. If you plan to use an airbag, follow the instructions for that particular system and garment; a UK46 label or a larger replacement size does not establish safe compatibility. Keep the product instructions for future changes to liners, armour or connected clothing.
