In the nonstop quest to find the perfect bar setup, I found a way to use the G-Craft damper mount with a Fatbar (in my case, risers too)



I used some RAM mount hardware, steel spacers, and half of a traditional Fatbar clamp. The result is satisfactory in my book. Hopefully the added length on the damper post doesnt create too much flex.

Spacer + bolt flexed too much for my taste.

A slightly shorter threaded post did the trick, and was 10mm shorter, even better. everything lined up pretty spot on.

Had some dyno tuning performed by the excellent Riderzblok shop here in San Diego, CA.

Headlight update, I like how clean it is, plenty bright even for night use.

CBR1000RR master. With the 4 pot Brembo, I feel I have more modulation. Not sure what the technical outcome is actually supposed to be.

Amazing weather this past weekend called for a ride out to Julian for a slice of pizza and a beer!

Finally dialed in my suspension and the bike has never handled better.

Looks good! May I ask what suspension changes were made? What tires are you currently using?

Runing Mitas MC35S tires. Expensive but will keep you glued to the road better than the rest. Poor lifespan on the street. Maybe try the MC34 next? Using a 100/120 combo, the bike dances from side to side.

I set out this weekend with the goal of making the bike a bit more confident being thrown into higher speed corners, especially after hard trail braking.

Most of the difference was made primarily dialing in the fork...playing around with firming up the compression a click or two and seeing how it affected the ride. The rebound side of the fork is maxed out all the way IN, with plenty of compression damping overhead left. This means that for my use, the Wt of fork oil specified was too thin.

Adding a bit of compression in the rear helped with the exits, it was squatting a hair under hard gas and would run slightly wide.

I've now learned many times over taking the time to focus on your suspension is the best way to make the bike go faster, safer. Especially if you are drastically under of over the target rider weight for a bike (160lbs)

First track day was a success. Headed out to Apex Kart track in Lake Perris.

86308


Never had ridden anywhere besides the street before, but settled in pretty quickly.
Some seriously fast kid on an Ohvale was out there lapping us like no tomorrow.

86309


First sign of trouble was grinding off my shifter toe peg by the end of the first session...
Suspension was performing bang on, no complaints all day.

86310


Bike performed well, low-sided once after getting too confident.

86311


Koso 4V broke a rocker arm the day before the track day, and I found replacements to use. Unfortunately, I think they went out of adjustment mid day as the bike started losing power past certain RPMs, and then kept losing more power as day went on.

Absolutely cannot wait to go back.

Oopsie...that rattling noise I heard mid session was the retention plate for the rocker arm pins coming loose. Amazingly, it wedged itself in the cam chain passage and the engine never lost timing...despite the pins backing out INTO the cam sprocket. Ho-lee-fuck.

That's what I get for not double checking my work when replacing the rocker arms the day before...nothing good ever comes from rushing your work to get the bike ready.

Time to find a new head...YIKES!

Thank you mister WV_Grom for not using the 4V head I sold you in 2018, and for letting me buy it back!

This current head is epicly done, camshaft, rockers, everything except the valves. Toast.

DAMN dude that was quite the catastrophic failure. Hopefully you get it back up and running soon.

Question: How do you feel about the differences between the Composimo Racebarz and the current bar setup you're running now. My current Protaper Honda Mini bars and the stock rearsets felt natural. When I added the Driven rearsets it didn't feel quite "balanced" like it should be a more forward and down like a supersport bike. Rotating the bars in the clamps didn't seem to make a big enough change. My initial thinking was get a set of flatter bars and risers for bodywork clearance. But the Composimo setup is clean and from the pictures I've seen is more forward and lower than almost any bar setup on the Grom I've seen. The convenience of swapping a bar on them is really easy in the event of a crash at the track too. I figured you would be the one to ask since you've done them both.

I just got it back together this past weekend, and put a few liters of oil through it to flush the case...magnetic drain bolt captured a few stray pieces. Thankfully the filter in the clutch cover caught the majority.

I liked the Racebarz, but for me combined with the Drivens, it put way too much weight over the front. Especially now considering I have to move the Drivens up a peg position because I was grinding all my control levers.

I think a flat bar is the way to go for comfort, and to still be fast. But, I never got to try the Racebarz at the track. Fatbar clamps I would recommend highly, opens up the options. I am using an OEM Magura bar from an old Triumph. Not too wide, not too much sweep, and not too much rise. Similar to a Protaper CR High with an inch or so cut off the ends.

I'm trying to get the Grom into more of a super sport bike position since i'm doing mostly track riding with it now, so the Racebarz might just be when I'm looking for. Thanks for the input, If the Racebarz don't work out for me, I'll look into FatBar clamps.
