Rolon HPXR 288 X-Ring Chain & Sprocket Kit for Jawa Standard / Jawa 42 – 13T/45T 98L

Genuine Rolon HPXR 288 chain & sprocket kit for Jawa Standard / Jawa 42.

Correct 13T front sprocket, 45T rear sprocket and 98-link chain setup for compatible Jawa Standard / 42 replacement fitment.

Fitment warning: This kit is for Jawa Standard / Jawa 42-type fitment. Do not assume fitment for Jawa Perak, Jawa 42 Bobber, Yezdi Roadster, Yezdi Adventure or Scrambler without exact kit-code verification.

Rolon HPXR 288 is a genuine chain and sprocket kit for Jawa Standard / Jawa 42. The verified setup is 13 teeth front sprocket, 45 teeth rear sprocket and 98-link chain. This is the main fitment detail customers should check before ordering because Jawa, Jawa 42, Perak, 42 Bobber and Yezdi models may use different chain-sprocket combinations.

This kit is useful when your Jawa starts showing drivetrain wear symptoms such as jerky pickup, khat-khat chain noise, chain slap, tight spots, rough throttle response, rusted chain links, hooked sprocket teeth or frequent chain adjustment. Replacing the front sprocket, rear sprocket and chain together helps restore smoother power transfer and prevents premature wear caused by fitting a new chain on worn sprockets.

HPXR 288 is a performance-focused Rolon kit for Jawa Standard / 42 riders who want correct OE-style fitment with a stronger drivetrain feel. The 13T/45T/98L setup keeps the motorcycle’s intended riding character for daily commuting, city riding, weekend rides and highway cruising without experimenting with altered gearing.

Use HPXR 288 only when your motorcycle matches the 13T/45T/98L setup and the front sprocket spline/rear hub pattern match. Under The Hood supplies genuine fitment-focused spares with careful packing and buyer support so riders get the correct Jawa chain kit instead of a mismatched generic 300cc-class kit.

Installation & Maintenance Notes

• Install at a professional motorcycle workshop for correct alignment, chain slack and torque.
• Replace chain, front sprocket and rear sprocket together; do not run a new chain on worn sprockets.
• Before installation, confirm your current setup is 13T front / 45T rear / 98-link chain.
• Check model carefully because Jawa Standard, Jawa 42, Perak, 42 Bobber and Yezdi models can use different kit applications.
• Check front sprocket spline and rear sprocket hub pattern before dismantling.
• Maintain chain slack as per the Jawa owner’s manual for your exact model.
• Clean and lube regularly, especially after rain, washing, dusty rides or long rides.
• Avoid direct high-pressure water jet on the chain and sprocket area.
• Re-check slack and wheel alignment after the first 200–300 km as the new kit beds in.
• Inspect rear hub dampers during installation; worn cush rubbers can still cause jerks even after fitting a new chain kit.

FAQ

Will Rolon HPXR 288 fit my Jawa 42?

Yes, if your Jawa 42 uses the 13T front sprocket, 45T rear sprocket and 98-link chain setup. Always verify the current sprocket setup if the motorcycle has been modified.

Will HPXR 288 fit Jawa Standard?

Yes. Rolon lists HPXR 288 for Jawa Standard / Jawa 42 applications. Match the 13T/45T/98L setup and rear hub/front spline pattern before dispatch.

What are the sprocket teeth and chain length?

The verified setup is 13T front sprocket, 45T rear sprocket and 98-link chain.

Is HPXR 288 an X-ring kit?

Some market listings describe HPXR 288 as an X-ring chain kit, while Rolon’s confirmed public specifications mainly show the kit code, application, teeth count and link count. For store trust, verify the current physical box/chain marking before publishing X-ring wording as a technical claim.

Is HPXR 288 a brass chain kit?

No. Do not sell HPXR 288 as a brass chain kit unless the current physical box specifically states brass plating.

Will this fit Jawa Perak or 42 Bobber?

Do not assume fitment. Perak and 42 Bobber have separate kit applications and must be verified by exact Rolon kit code, teeth count and chain length.

Will this fit Yezdi Roadster, Adventure or Scrambler?

No, not by assumption. Yezdi models should be checked with their own exact Rolon kit code and chain-sprocket setup.

Will this reduce chain noise, jerks and chain slap?

Yes, if the issue is caused by worn chain links, hooked sprocket teeth, tight spots, rust or incorrect chain adjustment. Also inspect wheel alignment, cush rubbers and rear wheel bearings.

Should I replace only the chain?

No. For best life and smooth running, replace the chain, front sprocket and rear sprocket together.

Why buy from Under The Hood?

Under The Hood focuses on correct kit-code fitment, genuine sourcing, safe packing and buyer guidance, which matters because the wrong rear sprocket teeth, chain length or Jawa/Yezdi model assumption can cause installation failure.
