Took these aluminum risers off my bike. They come with four stainless steel bolts shown for mounting each side, along with your stock bolts.
19MM thick/rise (approx 3/4")
These riser or HeliBars are designed to lift and bring your grips closer to you.
$50 in Penticton. Can arrange for them to me available in Port Moody for prepaid pickup.
May fit other years and models.
