2. Frequently Asked Questions (FAQ)

Q1. Can this be installed on standard 2024 or earlier models (MC49) or Rebel 250s without E-Clutch?

A. While it can be installed on older 2017–2024 models (standard clutch), this product (RB0198e) is specifically molded to match the E-Clutch case shape from 2025 onwards. The standard conventional under cowl (such as RB0176) is also available for 2024 and earlier models.

Q2. Can it be installed on the Rebel 500 or CL250/500?

A. No, this product (RB0198 / RB0198e) is exclusively designed for the Rebel 250 / 300. It cannot be installed on the Rebel 500 or CL series because the engine shape and bracket mounting points are different.

Q3. Is any special modification required during installation?

A. No shaving or modification of the bike body is required. It is a bolt-on installation using existing screw holes under the radiator and the provided L-bracket. As the fixing position requires fine-tuning, the task is intended for intermediate users.

Q4. Can it be installed while keeping the stock muffler?

A. Yes, it is designed to avoid interfering with the layout of the stock muffler and exhaust pipe, so you can install it while retaining the stock muffler.

A. No, this part number (RB0084e / RB0084-500) is designed exclusively for the Rebel 500. It is not compatible with the Rebel 250/300 due to differences in engine size and frame shape. (*For Rebel 250/300, please use the dedicated part number "RB0161J / formerly RB0084-300".)

Q3. Is modification required for installation?

A. It is designed primarily for bolt-on installation, but it is considered an "intermediate-level" part that requires the use of tools (screwdriver, hex wrench, etc.) for position adjustment and securing the included brackets. If you are not confident, we recommend having it installed at a motorcycle shop.

Q4. What should I do if the aluminum heat-shielding sheet inside the cover gets damaged?

A. The aluminum heat-shielding sheet attached to the inside of the cowl may deteriorate over time due to engine heat. If you notice any burning, degradation, or damage, please replace it with commercially available aluminum heat-shielding tape for motorcycles as part of your maintenance.
