Full details

The Alpinestars T-SP R Drystar Motorcycle Pants are designed for sport and sport-touring riders who demand versatility across changing weather conditions.

FAQs

Are these pants completely waterproof?

Yes, they feature an integrated Drystar membrane designed to provide a waterproof and breathable barrier against the elements.

Can I remove the thermal liner?

Yes, the 100g thermal liner is detachable, allowing you to customize the pant for warmer weather riding.

What protection is included in the knees?

The pants include DFS Lite knee sliders along with floating CE Level 1 GP extended knee and upper shin armor.

Are these suitable for track racing?

No, these are designed for sport-touring and road riding. They do not meet the specialized requirements of track-day racing suits.

How do I secure the waist?

These pants feature a convenient and secure magnetic buckle system that allows for quick adjustments.

Troubleshooting

Ventilation feels blocked

Ensure the internal fabric flap is not obstructing the vent opening and check for debris caught in the zipper teeth.

Waterproofing seems to fail after long use

The exterior fabric may have lost its DWR coating. Re-apply a textile-safe water-repellent spray to the outer shell to maintain performance.

Armor feels uncomfortable or shifts

Adjust the floating armor pocket straps and ensure the waist closure is tightened sufficiently to keep the pants in the proper position.

Pros and Cons

Pros

  • High versatility for multi-season touring
  • Excellent weather protection via the Drystar system
  • Highly adjustable fit at the waist and legs
  • Integrated CE-rated knee and shin armor
  • Convenient waterproof storage pockets

Cons

  • Not intended for track-day racing use
  • Textile material is less abrasion-resistant than full-grain leather
  • Heavier feel when the thermal liner is installed

Setup, Compatibility & Care

To ensure maximum safety, verify that the knee and shin armor sits correctly over your joints while in a seated riding position. The waist features a magnetic buckle closure that should be adjusted before starting your ride to ensure a secure seal.

Care Instructions:

  1. Remove the thermal liner before washing the outer shell.
  2. Use a mild detergent and a damp cloth for spot cleaning the 600D polyfabric surface.
  3. Avoid using harsh chemicals or machine drying as this can damage the waterproof Drystar membrane.
  4. Check the velcro and magnetic buckle points periodically for debris and wipe clean to maintain closure integrity.
