Plug wrench

Picked up this plug wrench for my 390RR to complete my toolkit. Quick shipping, good price.

Bad place to order from

Part is fine but I called and asked if this and an IMs dry break tank were in stock as I noticed they were on back order on the beta USA website. I was assured the stuff was in stock. It in fact was not In stock and took forever to ship

Fits as it's supposed to.

You can’t get better ! So happy

If you want the best , must be PRO BEND! Fits like a glove and took 15 minutes to transform my bike into that enduro bike that can take the beating on the bars ! RIDE ON

SLOW order fulfillment every time!

Ordered this as a Christmas present in November. Item showed “In Stock” on the website. Didn’t arrive until January. Last order I placed I paid for Next Day Air (also “In Stock) and was told when Sierra received it from the manufacturer they would ship it out NDA. That order was cancelled. Just be up front with delivery, my customers would never stand for misleading lead times like this.
