Spark plugs for your Yamaha XV535
The recommended plug is a BPR7ES. Match that code - spark plugs are thread-, reach-, and heat-range-specific, so the part number matters more than the brand. Worth considering: the BPR7EIX iridium upgrade - it fits the same port, fires cleaner, and lasts far longer between changes.

Frequently asked
What spark plug does a Yamaha XV535 take?
GarageDex's powersports data shows the Yamaha XV535 uses a BPR7ES spark plug, gapped to 0.032", or upgrade to the BPR7EIX iridium plug. Spark plug fitment varies by year - see the table for each range.
What is the spark plug gap on a Yamaha XV535?
The Yamaha XV535 spark plug gap is 0.032". Set the gap with a feeler gauge before install - iridium plugs come pre-gapped but always verify, since a wrong gap causes misfires and hard starts.
Are iridium spark plugs worth it on a Yamaha XV535?
The BPR7EIX is the iridium upgrade for the standard BPR7ES. It fits the same port and heat range, fires more reliably, and lasts far longer between changes - a worthwhile swap for most riders, though the standard plug is perfectly fine if you change plugs on schedule.
Does the Yamaha XV535 spark plug change by year?
Yes - the fitment differs across the years we cover: 1987-1990 uses BPR7ES; 1981-1983 uses BPR7ES. Match your exact year in the table.
How often should I change the spark plugs on a motorcycle?
Standard plugs typically want replacing every 8,000-12,000 miles (or per your service manual); iridium plugs go much longer. Fouled or worn plugs cause hard starts, misfires, and poor fuel economy - a cheap part that punches above its weight.
