Equivalent Battery Options for YTX9-BS (8 Ah / 135 CCA) in India

Original GS Yuasa YTX9-BS: This is the factory battery specification for a 2022 Kawasaki Versys 1000. It’s a 12 V, 8–8.4 Ah capacity battery (8 Ah at 10-hour rate, about 8.4 Ah at 20-hour rate) with 135 A cold-cranking current (CCA). Dimensions are approximately 152 × 88 × 106 mm (L×W×H). Any equivalent replacement should closely match these figures in capacity, CCA, and size.

Below are Indian-market equivalents from Exide, Amaron, Tata Green, and others, with their specifications compared:

Exide Xplore XLTZ9 (YTX9-BS Equivalent)

Capacity: 8 Ah (12V VRLA AGM type). (Exide markets this model as “Z9” in the bike battery range.)
CCA: ~120 A (EN) cranking current, slightly lower than Yuasa’s 135 A. (This is Exide’s own specification for the YTX9-BS format.)
Dimensions: ~150 × 87 × 105 mm, which is essentially identical to the original battery size, ensuring proper fit.
Notes: Maintenance-free (sealed VRLA) design with 48-month warranty in India. Built for motorcycle use and commonly used in bikes of similar class. Exide’s XLTZ9 “Xplore” series battery is designed for high cranking performance and rugged conditions. It is a direct replacement for YTX9-BS in size and voltage.

Amaron Pro Rider APBTZ9R (YTX9-BS Equivalent)

Capacity: 8 Ah, 12V, maintenance-free AGM construction. (Sold as Amaron Pro Bike Rider “Z9R”).
CCA: Not explicitly published by Amaron. In practice it is designed for high-cranking performance similar to other YTX9-BS batteries (expected in the ~120–130 A range). Amaron describes this model as suitable for bikes up to 350cc and other high-end bikes, indicating robust cranking ability. (No official number is given, but it should be comparable to Exide/Yuasa.)
Dimensions: 150 × 87 × 105 mm, matching the YTX9-BS spec for a drop-in fit. Terminal layout is the same (positive on right-hand side typically, labeled as “R”).
Notes: This Amaron Pro Rider battery is a zero-maintenance, factory-charged AGM battery. It comes with a 48-month warranty. Riders report that it provides high cranking power and reliability similar to OEM batteries. (It’s commonly used for bikes like KTM Duke 390, Royal Enfield Himalayan, etc., which indicates it can handle large engines – the Versys 1000’s requirements should be similar.)

Tata Green Velocity Plus TGZ9 (YTX9-BS Equivalent)

Capacity: 8 Ah, 12V, VRLA battery. Tata’s code for this model is “TGZ9” in the Velocity Plus series.
CCA: Not explicitly listed by Tata Green. Given that Tata Green Batteries are made with GS Yuasa’s technology, the cranking performance is expected to be on par with the original GS Yuasa (around 135 A CCA). Tata Green markets this battery as having “high cranking power”, leveraging GS Yuasa’s design. (No exact CCA figure is published, but performance should closely match OEM specs.)
Dimensions: 150 × 87 × 105 mm, identical to YTX9-BS standard dimensions for compatibility.
Notes: Tata Green is a joint venture with GS Yuasa, and this Velocity Plus TGZ9 battery is essentially the GS Yuasa design built in India. It features advanced Japanese AGM technology. Warranty is typically 24 months flat + 24 months pro-rata. This battery is a “genuine GS Yuasa technology” product, so quality and performance are at OEM level. It’s often recommended for Royal Enfield 500, KTM 390, etc., and is a suitable replacement for the Versys 1000’s YTX9-BS.

Other Equivalent Options in India

Aside from Exide, Amaron, and Tata, there are a few other brands that offer YTX9-BS equivalents, all of which closely match the 8 Ah capacity and roughly 130±15 A CCA range:

SF Sonic (Exide’s sister brand): Model TZ9 (e.g. SF Sonic 48S-TZ9) – 8 Ah, AGM VRLA with 48-month warranty. It is essentially the same spec as Exide’s Xplore series since SF Sonic is part of Exide. CCA is not officially stated, but it’s designed for “excellent cranking performance” (multiple starts) in bikes like Royal Enfield 350/500, KTM 390, etc.. Dimensions are standard 150×87×105 mm (direct YTX9-BS size). This is a viable substitute that will fit and perform similarly.
Bosch: Bosch offers a YTX9-BS replacement (often labeled M6 010). It is a 12V 8 Ah AGM battery, with a claimed CCA of 135 A – essentially equal to the Yuasa spec. Dimensions are 152×88×106 mm (as per JIS YTX9-BS standard). Bosch’s battery is known for meeting OEM specifications; a Bosch YTX9-BS will provide the same 135 A cranking power as the original Yuasa. It may be available through select importers or dealers in India.
Others: There are also generic or international brands like Power Sonic, Yuasa (imported), Rocket/Globatt, etc., which make YTX9-BS format batteries. For example, many aftermarket YTX9-BS AGM batteries (from brands like Casil, ChromeBattery, etc.) advertise ~8 Ah and ~135 CCA. If sourcing from motorcycle part shops, one might also encounter AMCO or Okaya two-wheeler batteries in this size. The key is to ensure any alternative has 8 Ah capacity and ~135 A cold cranking current, and the same case size (to fit the battery compartment). Most reputable brands’ YTX9-BS equivalents will meet these requirements.

Comparison Summary (Ah, CCA, Dimensions)

GS Yuasa YTX9-BS (OEM) – 8.4 Ah (20HR), 135 CCA, 152×88×106 mm.
Exide Xplore XLTZ9 (Z9) – 8 Ah, 120 CCA (EN), 150×87×105 mm.
Amaron Pro Rider Z9 (APBTZ9R) – 8 Ah, CCA ~120–130 (not published; designed for high cranking), 150×87×105 mm.
Tata Green Velocity Plus TGZ9 – 8 Ah, CCA ~130+ (not published; GS Yuasa tech), 150×87×105 mm.
SF Sonic 48S-TZ9 – 8 Ah, CCA not stated (~120+), 150×87×105 mm (same as Exide Z9).
Bosch YTX9-BS (M6 010) – 8 Ah, 135 CCA (matches Yuasa), 152×88×106 mm.

All of the above batteries are 12-volt, maintenance-free AGM types suitable for motorcycles. They will be close alternatives to the YTX9-BS in a Kawasaki Versys 1000. In practice, any of these with an 8 Ah rating and around 120–135 CCA will crank a 1000cc engine reliably. Just ensure the physical size and terminal orientation match the original (which these models do).

Each brand’s offering comes with its own warranty and brand reputation, but performance-wise they are comparable in this category. For example, Exide and SF Sonic may have a slightly lower CCA (around 120 A) than the Yuasa, whereas Bosch and Tata (GS Yuasa-tech) are at the full 135 A mark. Amaron is also known for strong cranking batteries in this segment (often reported to perform on par with Exide/Yuasa in real-world use). All listed options are commonly available in India through battery retailers or bike dealerships.

Bottom line: You can replace the YTX9-BS with Exide’s XLTZ9, Amaron’s APBTZ9R, Tata Green’s TGZ9, or similar batteries from SF Sonic, Bosch, etc. – all offering ~8 Ah capacity and ~130 A cold-cranking performance, in the correct size for a Kawasaki Versys 1000. Each of these meets the required specs (12V, ~8 Ah, sufficient CCA) and will fit the battery compartment, making them suitable equivalents for the original GS Yuasa YTX9-BS. Be sure to compare warranty and price, but any of these will power a 1000cc motorcycle with no issues, providing a close match in Ah and CCA to the stock battery.

Conclusion

For a 1000 cc motorcycle replacing the OEM GS Yuasa YTX9-BS, any of the six Indian-market options above will physically fit and supply adequate cranking power:

Closest match to OEM spec: Bosch M6 010 (identical 8 Ah / 135 CCA) and Tata Green TGZ9 (Yuasa tech, same capacity, expected CCA).
Best warranty: Tata Green TGZ9 (54 months) edges out Exide/Amaron/SF Sonic (48 months).
Higher-performance upgrade: Tata Green YTZ10S delivers +1 Ah capacity and a robust 190 CCA—ideal if you want stronger cold starts or run extra accessories; just add a 13 mm spacer.
High-availability value picks: Exide XLTZ9 and Amaron APBTZ9R are widely stocked nationwide, with CCA 120–130 A—still ample for a litre-class engine.

Choose based on the balance you prefer between price, warranty length, and extra CCA headroom; your Versys 1000 will crank reliably with any of these AGM replacements.
