lower your bike-rear shock
We all know you can slip the front forks down a bit and lose a half inch of seat height or more, depending on your bike.
But dog leg adapters (longer) are typically used to drop the rear of the bike. This might work with the Templar bikes, The "doglegs" are welded to a steel cylinder (bushing). That bushing and other dimension will need to match. This is probably GOOD for stiffness in the suspension, but the doglegs can't be simply replaced. But this is OK, because the shock itself has a lower mounting "opportunity". In fact, here is a KTM replacement shock I found on AliExpress. There are TWO options for height (mounting on the lower linkage): The same thing applies to the OEM shock on the Templar, but you have to drill new holes. I don't have time this Fall to work on this, but feel free to get going on this simple mod if you have time and want to lower the bike: Last edited by Thumper; 04-20-2024 at 09:26 PM. |

Does it look like you would have cut the excess off if you drilled new holes? From what I remember the lug on the bottom of the shock mount is just a stop for the head of the mounting bolt. I'm not really worried about the resale value, and lower would be really nice.
Was there room to get the shock out from above? Mine is 2500 miles away, but that looks like low risk, easy and a good idea. |

The excess just points down, not even beyond the rest of the linkage. I would leave the original in place (just like that KTM has both positions) in case you ever need to raise the bike again.
And, make sure that you drill a hole with the exact same size, and that the hole is parallel. When I get around to this, I will set the thing sideways on a block of 2x4 under the bit on my drill press to make sure that the holes are at exactly the same position on each side. If you drill to oversized hole, a bushing could fix it. The bolt/pin that secures it has a smooth area where it contacts the shock mount, and it is a snug fit (no play). But best to drill the exact diameter hole. Buy a drill bit if you have to. Oh, and the lower hole has a raised flat end block to hold it in place while you tighten the nut. That is convenient, but as long as you use a good locking thread nut (like the one it comes with-teflon ring, as I recall), it should stay in place. It will just be necessary to get an adjustable wrench on that flat bolt head to get the locking nut tightened on. You can always get a new locking nut if needed. Quote:

Thumper,
Thanks, I like this a lot. Had not though of putting a block on the drill press table to locate the holes, I would have measured (I get it right most of the time..). As long as both "legs" of the mount are the same length (I am going to measure, but you would think they would be) I think using the block is good, and maybe/probably faster, and if you're me, some of the time, more accurate. Thanks again. Pat |

I really want try this. I need too remove the shock again. I think I pulled it out the right side after removing the head pipe and carb. That was during assembly.
I need to measure the swingarm pivot point to axel and distance to the lower shock mount to calculate the position to drill. If shooting for 2.5 inch lower, where do you drill? It should be a simple proportionate amount of 2.5 based on the ratio of distances, assuming the new geometry does not significantly affect compression. My son can check the math. |

I will edit/add the photo of the new drilled hole (I posted it before in another thread). But useful to have this here. It needs a 10mm hole. This is aluminum, so it drills easily. Make sure you have the lower forks level on the drill press so you drill straight across the fork: Last edited by Thumper; 01-02-2023 at 11:48 AM. |

I was looking at my KPX shock over the weekend. It has two set of holes in the shock already but was already set to the lower position. I don't have enough room to drill another set of holes to lower it any more. I wouldn't mind lowering the rear about another inch. Hopefully the springs will compress a little as the springs settle in. It already feels like it's setting a little lower than when new.

Done!
I completed the lowering project this weekend. It resulted in about a 3" lowering of seat height, which is exactly what I wanted:
I used loctite on the connections at the linkage. The first 3 inches of shock travel ("sag") happens when you sit on the bike (STOCK condition). That would put the rear tire closer to the rear fender with a shorter shock, SOoooooooo... In addition to shortening the effective shock length by 1", I added more than 350lb to the PRELOAD to take up that 3" and now it BARELY SAGS when I sit on it. I don't have the correct spanner tools to loosen the lock ring and turn the preload collar, and even if I did, that is a heavy spring, and you can gnarl up the collar badly (it is aluminum!). Those are aluminum threads as well, I don't like the idea of grinding them against a heavy duty coil spring anyway... So, I used a coil spring compressor to make it easy to tighten the collar: Last edited by Thumper; 01-02-2023 at 05:45 PM. |

Coil Spring Compressor mod
The coil spring compressor was designed for a wider coil spring, so I pinched the spring hook plates in the vice.
The hooks aligned well enough now, BUT the hooks hit the threads (collar/cuff threads) threatening to damage them, so I used the dremel to cut of the excess: Now the clamps fit, and ready for use. You can see the gap between the collar and the top of the spring. Turning the collar/cuff was easy once the coil spring was pulled: I left the locking ring in place to keep track of how much I was tightening the spring. I ended up at more than 1", but here it is at about 1" Last edited by Thumper; 01-02-2023 at 11:49 AM. |

Preload adjusted
I used a 3/8" breaker bar to make the job easier. Pinning the shock on the table and against my waist with my left arm, and tightening with my right arm. It wasn't bad.
Job done. I probably added more than 350 pounds of preload (you can see it is more than one inch tighter). Locking ring is tightened onto the collar. It is ready for reinstallation. |

Test ride
It is much easier to mount the bike, and it sags about an inch when I put my weight on it (not 3+ inches sag with OEM setup!). I also dropped the front end to the sixth ring to lower the front. You can see the front fork drop in these pics:
The kick stand is barely short enough now. In the garage, I put a block of wood under the rear tire (not level in the garage). I took it on my nearby single track and quad trails. The bike feels the same because I have essentially taken the sag out of the picture. The only noticeable difference is that the rear shock does not extend as far on jumps. I did also stiffen up the compression and rebound settings. I like this! It is less "springy", and stiffer. For me, it feels more controllable, and easy to get on/off. This is a viable strategy to lower any of our monoshock bikes (if there is room on the lower mounting fork on the shock). I went 1 full inch, and got about 3" of lowering on the Templar. 5/8" or 7/8" might work better for some bikes, or if you want less lowering on the Templar Last edited by Thumper; 04-19-2023 at 09:18 PM. |

Cut holes 1" longer than stock or so, and give it a try. |
