With a little bit of filing. Actually quite a bit of filing on the bench top spindle Sander I got enough clearance between the engine and the bracket to fit it on. Even have to sand the inside radius for a better fit. But everything snugged up well and I have about a quarter of an inch clearance between the bracket and the engine
Why such a thick bracket? A small thin steel bracket would be as strong and may provide up to an inch clearance. I'm thinking almost any bump would move the bar more than 1/4" and damage your engine: what they are supposed to prevent in the first place. You can get universal brackets at Home Depot and drill, clip, and bend them yourself pretty easily. The thick aluminum brackets look beefy and nice, but not nice enough to chance damaging my engine anyway. ymmv (i.e. - tight clearance (to engine) in crash bars may not be good if you crash)
Of couse that could be fixed easily, so it may still be the best option for crash bars
Agreed that this may be an overbuilt design. But if you lay the bike down hard enough to bend the main tube of the frame... I think you're going to have bigger problems than damage to your engine. Overall I'm very pleased with the fit and finish of these bars. They look very well-built and they appear to give good protection.
By the way these bars were purchased off of eBay.
The vendor was very responsible as I was short one bracket and they expedited parts to me with in a couple weeks. I was very pleased with their customer service.
2 months ago last ride of the year I low sided this bike at 40 mph.
I was blessed with a bent bar and ground off foot pegs. Luckily no other damage. What a horrible sound hearing your bike spin down the road.
Just waiting for 17/19 wire wheels.
