TVS N7110380 Rear Brake Master Cylinder Assembly for Apache RR 310 (BMW 310 R/GS/RR Retrofit ) – Genuine TVS OEM

The TVS N7110380 Rear Brake Master Cylinder Assembly is the genuine OEM rear master cylinder used on the TVS Apache RR 310. In the official RR310 BS6 parts catalogue, it is listed as “N7110380 – MASTER CYLINDER ASSY. REAR”, complete with piston, seals, and internal hardware for the Apache 312.2cc platform. 

If your rear brake feels spongy, leaks fluid, or the bike has had a right-side crash, replacing the complete master cylinder is the safest, long-term fix. Unlike local rebuilds, the genuine N7110380 maintains factory-spec bore size, pressure build-up and compatibility with the dual-channel ABS system on the RR 310. 

Because the TVS Apache RR 310 and BMW 310 series (G 310 R/GS/RR) share the same 310 platform co-developed by TVS and BMW, many workshops and online sellers retrofit TVS hydraulic parts (pads, cables, some hydraulics) to BMW 310s for cost-effective maintenance. The N7110380 master cylinder matches the Apache/BMW 310 rear disc/ABS layout and can be used as a retrofit option on BMW 310 R/GS/RR, but this cross-use is not officially listed in BMW EPC. 

For Apache RR 310 owners, this is the exact replacement part. For BMW 310 riders, please confirm dimensions and mounting with your mechanic before ordering.

FAQs 

Q1. Is N7110380 a genuine TVS part?
Yes. It appears as “MASTER CYLINDER ASSY. REAR – N7110380” in TVS Apache RR 310 parts catalogues and TVS MRP lists. 

Q2. Will this fit my Apache RR 310 BS4 / BS6?
✅ Yes. This is the exact rear master cylinder used on Apache RR 310 across BS4 and BS6, as confirmed by TVS catalog and multiple OEM-focused sellers. 

Q3. Can I use this on my BMW G 310 R / GS / RR?
It can be used as a retrofit on BMW 310 R/GS/RR because they share the same 310 platform and many workshops already use Apache/TVS parts on BMW 310s to reduce costs. However, BMW EPC does not officially cross-reference N7110380.

Q4. Does this master cylinder include the reservoir and hose?
By TVS kit list, N7110380 covers the master cylinder body and internal components; the reservoir and hose are separate items. Under The Hood will ship exactly what is visible in our product photos. 

Q5. When is it better to replace the whole master cylinder instead of just bleeding?
If you have oil leaks, a sinking pedal, internal corrosion, or repeated loss of pressure even after proper bleeding, replacing the entire unit with a new N7110380 is safer and more reliable than trying to rebuild a badly worn cylinder.
