It offers stronger bottom end torque than stock with a very smooth delivery that wont break traction too easily. It enables the rider to use lower revs and less clutch when tackling hard obstacles. The low comp design also offers maximum resistance to overheating in tough situations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMEDIUM COMPRESSION\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e– This head  suits the majority of trail riders and racers who want better bottom and mid power and a gain up top as well. The power delivery is much stronger and more tractable than stock and suits a wide range of riding conditions. Designed for 89 or 91 octane fuel.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHIGH COMPRESSION\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e– This head suits riders who want harder hitting power everywhere, especially down low, and are happy to sacrifice some over-rev to achieve this. It completely transforms the bike into a weapon, but can be a handful in some situations at sea level. It can also be used at higher elevation (above 3000′) to achieve a similar power delivery to the medium compression head at sea level. Must use with 91 octane fuel at sea level). We don’t recommend using this design for extreme enduro due to the increased tendency to overheat in very tight, technical riding near sea level, or for high revving applications like desert racing or supermoto. Best to use the low or medium designs for those applications.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e","brand":"TSP","offers":[{"title":"2018-2024 \/ Low Comp","offer_id":46680942412021,"sku":"PWRKITCARB-SH300.ERM.18.L","price":845.0,"currency_code":"USD","in_stock":true},{"title":"2018-2024 \/ Medium Comp","offer_id":46680942444789,"sku":"PWRKITCARB-SH300.ERM.18.M","price":845.0,"currency_code":"USD","in_stock":true},{"title":"2018-2024 \/ High Comp","offer_id":46680942379253,"sku":"PWRKITCARB-SH300.ERM.18.H","price":845.0,"currency_code":"USD","in_stock":true},{"title":"2025+ \/ Low Comp","offer_id":46680942510325,"sku":"PWRKITCARB-SH300.ERM.25.L","price":845.0,"currency_code":"USD","in_stock":true},{"title":"2025+ \/ Medium Comp","offer_id":46680942543093,"sku":"PWRKITCARB-SH300.ERM.25.M","price":845.0,"currency_code":"USD","in_stock":true},{"title":"2025+ \/ High Comp","offer_id":46680942477557,"sku":"PWRKITCARB-SH300.ERM.25.H","price":845.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/2782\/files\/tsp-erm-power-kit-sherco-300cc-2018-93184612.webp?v=1751153811","url":"https:\/\/mojomotosport.com\/products\/tsp-erm-power-kit-sherco-300cc-2018","provider":"MojoMotoSport.com","version":"1.0","type":"link"}
